What does ISE actually mean?
An ISE is an Ion-Selective Electrode. It converts the activity of a specific ion dissolved in water to an electrical potential.
What is the "lifespan" of these ion electrodes?
i.e. for how many measurement-cleaning-calibration cycles can they be reused…¿
There is no fixed number for average number of samples for probe exchanging, although we usually use a minimum basis of 500 samples. There are probes that usually go far beyond that number without loss of sensitivity and others that hardly get to 500. Each probe works as an individual, when one sensor is off, the others continue working properly. The replacement is also done individually.
If the probes are used every day, the minimum average number of samples is multiplied by a factor of 2 (#1000 samples) The more frequently used, the higher the performance in number of samples.
Also, this sensitivity is highly related on the storage and careness. The maintenance is done by rinsing with water, properly drying and getting it stored in its plastic cap in a room temperature conditions. The number and matrix of samples and aging also affects them.
What’s the error margin of the electrodes?
The best precision in ideal conditions is 4%. In usual conditions it’s accepted the comparative with other thechniques of up to 15% for monovalents and 20% for divalents. The ammonium, chloride, nitrate, potassium and sodium have a +/-10% margin error. Magnesium and calcium have a +/-20%.
What are the accuracy and repeatability of these electrodes?
Please find attached the general specifications table for each parameter. As general is a 4% Accuracy and 10% Repeatibility.
How is a sensor replaced?
It’s done individually and it only requires tweezers. Please refer to this video: https://www.youtube.com/watch?v=BkmbfXaY8Fo
Do I need to replace all sensor if one has run out?
No, each sensor works individually. Even though one is used up or damaged, the rest continue working properly.
Is it needed a specific product to clean electrodes to avoid possible contamination?
You must clean them with DI water and store them after being sure they are dry.
Are your sensors range able to test other kind of micro elements in the soils other than the 7 in the Imacimus 10?
We manufacture other type of sensors besides the 7 from the multiion application. They are usually sold as individual electrodes as they require a methodology for low concentration range of sensors.
What do References Electrodes measure?
The reference electrode does not measure anything, it works for closing the electrical circuit for all the sensing electrodes.
What type of water should ISE sensors be used in?
Use Ammonium and Nitrate sensors in fresh water whose specific conductivity is less than 1000uS/cm. Sodium is a majorinterference for Ammonium and Chlorate ions are major interferences for Nitrate activity. Chloride sensors suffer interferenceswhen the concentrations of bromide, iodide, cyanide, silver, and sulfide ions are much higher than the chloride ionconcentration.
What is the maximum submersion depth of ISE sensors?
Maximum of 15 meters for all ISE sensors. If deployment exceeds 15 meters, the ISE sensor must be removed and a dummy plug(included with sensor) must be installed in the sensor adaptor or the sensor will be damaged.
What is the life expectancy of ISE sensors?
Ammonium and Nitrate sensor tips will last from three to six months whether they are stored on a shelf or installed in a sonde.Chloride sensor tips may last a year or more in the same conditions.
What are ISE sensors best suited for?
The ISE sensors are best suited for spot monitoring activities. These sensors drift more than other sensors and are not well-suited for long-term deployment. Do frequent QA/QC and calibration on ISE sensors, especially ammonium and nitrate, if theyare to be used for extended deployment
We use the equipment for seasons...
We use the equipment for seasons… and we last several months without using it. What care or maintenance should we give during that time period that we do not run sap sampling?
There is no regular maintenance. Clean (With deionized water), let dry before capping with plastic cap, and store in a dry place away from sunlight and high temperatures in the equipment after each use. The fungible part of the equipment must be renewed when they are exhausted.
Can two or more of the electrodes be use in the same sample solution for simultaneous measurements?
Yes, of course.
They share a common reference electrode for all electrodes. Please review the Imacimus Series, that uses our innovative multi ion probe for measurement up to seven different electrodes to be handled as just one handy probe.
Can I leave the probe waiting in the last analysed sample?
Never. It must be retrieved immediately and rinsed with DI water.
What are the advantages of your sensors compared to other sensors?
Advantages of our sensors:
– NT Sensors electrodes are made with our patented technology
– All-solid-state selective electrodes are based on Carbon Nanotube Technology
– Miniaturized Ion Probe
– Single Ion & Multi Ion Probe options
– Allow to work in all positions (horizontal/inverse)
– No light or ORP sensitivity
– Affordable
– Easy replaceable tips
How should I store the electrodes between use sessions?
In general, for overnight or longer storage, ISEs should always be rinsed with de-ionised water and gently dabbed dry with a low-lint tissue, and the black plastic cap should be replaced to protect the membrane from atmospheric oxidation/corrosion.
Reference electrodes must be prevented from desiccation whenever they are not in use by replacing the protective cap containing a small quantity of the appropriate outer filling solution.
Where can the sensors be connected?
All our electrodes are compatible with any commercial mV/ION meter from the market. They just need a high-impedance channel, with 0.1mV resolution.
Is it compatible with other mV meters?
Our electrodes are compatibles with meters or equipment using a BNC termination. Our Single Probe can be connected to any mV/Ion meter that has a BNC connection. Be aware that the Single Probe is a half cell electrode, so it’s necessary to connect a reference electrode as well away from the meter to be able to work.
So, if the meter has a reference input + BNC (for half cell ions) then the reading can be obtained using our electrodes. If the meter only have one input channel (1 BNC for both ref/ise) then it won’t be functional. If it can be 1 banana plug for the ref + 1 BNC for ISE/pH then it will work, because our ISE ar e compatible with the majority of ion meters in the market.
What is the minimum non volume of the non-diluted solution to be measured?
It depends on the sensor model, usually a drop is the minimum quantity. The tip surface must be in contact with the sample.
For standard Mini 2.5 it is around 100uL and for the Mini4.6/Single Ion of 12mm the mimimum is around 5 mL
In what kind of analysis is the use of the pH carbon nanotube recommended?
In food or process industries, or where they do not have sufficient sample volume.
Does the pH carbon nanotube probe need to be conditioned before calibration at pH 4 and pH 7?
Yes, a few minutes at pH 4.
This probe needs a Reference to work with, and is only used in particular cases where normal ones cannot be used.
What is the difference between the pH probe and the unique (carbon nanotube) probe?
The more classic pH is a combined probe and includes reference and a part of glass. The unique probe is designed with a polymer that allows you to work in industries where you cannot measure with crystal.
I’m interested in an instrument or product able to measure soil pH
Our Imacimus 2 equipment measures pH from a soil extract (taken from a lisimeter, dissolve a portion of soil in DI water). This measurement is the usual one for agriculture. However, in NT Sensor we don’t provide specific equipment to measure directly staying in the soil as a solid material.
How and where is the pH electrode stored?
Can I store it in DI water?
It must be stored in its high concentration KCl solution. Never store it in DI water.
Can the equipment be corroded?
What is the possibility that the equipment could be corroded by the presence of salts, acids and toxic metals in the water?
Usually the equipment can withstand this type of elements. Sensors can decrease in life or sensitivity, requiring more frequent renewal.
Microalgae adhesion in the probes?
Before microalgae adhesion in the probes, What is the right way to clean without damaging carbon nanotubes?
Rinse in deionized water and let dry before storing. No special treatment. When the sensor is exhausted, replace.
On probes how to avoid mineralization?
What care should be given to probes to prevent mineralization?
None special. Keep 1 minute per sample, then remove probes and rinse with plenty of deionized/distilled water.
What type of cleaning should be performed after the sample analysis?
What type of care or cleaning should be performed on the probes after the sample analysis is performed?
Exactly the same. Keep 1 minute per sample, then remove the probes and rinse with plenty of deionized/distilled water.
Analysis on a sample of brackish and marine water?
What kind of care should be taken with the multi-ion probe before and after the test is performed on a sample of brackish and marine water?
This type of water does not affect the sensors. It is necessary to use solutions for this type of medium. There are ions with low concentration that in seawater, the sodium chloride concentration will affect the measurement and there will be more error in the measurement.
If probes can’t be continuously monitoring a sample, how can I do it then?
There are 3 different options to continuous monitoring available:
1) Collect all the measurements of the day (or per week), and try to get the measurements all together (it takes around a 1 minute per sample when calibrated)
2) Use the probes in a measurement cell/ recipient. Just make sure the probes are left in the air between measurements, and use a small pumping system to fill in the sample.
3) Move on to an automatic system (see our catalog and contact us for more information).
Can I measure the three parameters nitrite, nitrate , bromide, with the same probe?
The imacimus 5 head can hold up to four sensors. Although, we only manufacture multi-ion standards for seven compatible ions (Ca/Cl/K/Mg/Na/NO3/NH4). Other ions, such bromide or nitrite, can work in the multi-probe head. Although they must be calibrated by individual salts, and therefore the measurement can be simultaneously performed.
Take note that this procedure needs some laboratory user, that knows about salts and compatibility of interferences to work with. It is not difficult, although we usually recommend acquiring a single ION head for in case you prefer to just calibrate and measure item by item.
Can I use the nitrite electrode in a multiprobe?
The nitrite tip can fit into a multiprobe. However, due to the ease of oxidation of the nitrite ion and calibration standards, we highly recommend to use it separately using a Single ION probe.
They are also interested in measuring more trace elements?
Do you have a solution for that or are you working on a solution for that?
Apart form the sensors included in Imacimus 10, we also produce nitrite, perchlorate, bromide, iodide, fluoride, lithium. Silver and Copper may be produced on request (back order). Please note these sensors work individually, with the Single Ion Head.
Can wastewater contaminants damage equipment probes?
Do not damage them, but can affect their lifespan.
What are the best practices for calibrating the HL series ISE sensors?
Rebuild the reference if needed, and calibrate conductivity and pH before calibrating any ISE sensor.
Calibrate ISE sensors with standards that either bracket your expected measurements or that are close to what you expect tomeasure.
The ISE sensors need frequent maintenance and calibration compared to other water sensors. ISE calibrations do not last as longand will drift faster. Bio-fouling and water conditions will affect maintenance and calibration frequency. A difficult to calibrate ISEsensor indicates that it needs to be replaced.
Before calibrating a new sonde with ISE sensors, soak the sensors in the calibration cup with a high conductivity standard, like47.6 mS/cm, for 2 to 4 hours to condition the reference electrode. When the reference mV is stable, it is ready.
Soak a new ISE sensor in any of its standards overnight to condition it. It will calibrate more easily.
To calibrate an ISE sensor reliably will take a minimum of 20 minutes per sensor. ISE sensors need more time to stabilize thanother sensors during calibration as well as during measurements in the field.
For best results, calibrate the ISE sensor at or near the water temperature it will be sampling. In any case, be consistent in yourcalibration temperatures.
When calibrating sensors, it is important to use deionized (DI) water to rinse between calibration steps.
If at all possible, use a stir plate to calibrate ISE sensors. Keeping the standard well-mixed improves calibration stability.
What are the best practices for installing the HL series ISE sensors?
When installing, be sure to calibrate pH and conductivity first and then ISE sensors as a best practice.
Sensors work best in flowing water. We recommend choosing a site in a location with good water flow to ensure movement ofwater over the sensor.
After placing the sonde in the water, allow several minutes for the sensors to stabilize for consistent measurements.
mold and fungus!?
Bad practices can generate the appearance of mold and fungi, do the probes of the IMACIMUS team has any protective film to prevent the appearance of fungi and mold?
Plastic parts can be cleaned thoroughly. Electrodes should only be rinsed with deionized water and dried.
Are your sensors range able to test other kind of micro elements in the soils other than the 7 in the Imacimus 10?
We manufacture other type of sensors besides the 7 from the multiion application. They are usually sold as individual electrodes as they require a methodology for low concentration range of sensors.
What’s IMACIMUS for?
Imacimus is a tool that provides information about macronutrients in an easy and reliable way to be able to better manage cultivation and lowering costs of precision agriculture. (feritirrigation system, hydroponic recirculation system, sap analysis, soil extract, foliage, water, drainage and so forth). Calibrates, measures and shows simultaneously up to 10 parameters (7 ions + pH + conductivity + water hardness) in real time and you just need a minute per sample.
Measurements are saved directly in an Excel (.csv) file. The meter is portable and requires a Windows System (pc or laptop) to run the software. Doesn’t need power supply, only a USB port.
What’s the technique based on?
The IMACIMUS is a MultiION meter based on electrochemistry technique, Nernst Law, with the innovation of a patented technology of carbon nanotubes inside.
It is a quantitative instrument with lab accuracy, and like any other laboratory technique, it depends on the user. Each electrode has got detection limits. For more info related to that please take a look on the specifications datasheets.
The electrodes are fungible, and they are spare parts that must be replaced by the user time to time.
How do I start using the equipment?
Please follow the steps of our users guide and First steps videos here
Can Imacimus results be compared with laboratories results? Is there any study/document with comparative related information?
Imacimus is a lab equipment, based on electrochemistry, so the results are comparable to any laboratory measurements. Electrochemical instruments offer quantitative determination on the ionic species (parameters), with high accuracy.
It also depends on how the user takes care/manages the equipment. If the sample is in within the same conditions, the Imacimus results are within the same basis as any other lab report.
I’ve attached a technical report showing related comparative information of Imacimus vs other labs, that was held a few years ago by an independent party.
Is it necessary a periodic maintenance for the equipment?
No, it’s not necessary. Clean with DI water and dry-store after each use. When a fungible part is not operating, it must be replaced.
Can I read the Single Ion probe simultaneously with Imacimus?
Yes, the meter can be used both with Single Ion probe and Multi Ion probe, although it must be done separately.
EC on imacimus
Conductivity is related to the ionic composition/quantity and mobility on the ionic species therein. Commonly, it is measured through a specific conductivity probe (a physical sensor).
But Imacimus 10 provides the reading of the major part of the ions in the solution. Our R&D team obtained a direct relationship from Imacimus 10 overall ions, and came up with a theoretical calculation for the expected EC in the samples.
Therefore, Imacimus 10 determines the ions’ concentration and shows up a theoretical value calculated from a reading. There’s no specific EC sensor for it, as it is calculated through a formula. Generally, Imacimus has a similar correlation with other EC market sensors.
How’s conductivity measured?
Conductivity is a theoretical value calculated from the basis of ionic balance by the reading of most part of ions. There’s no specific sensor for it as it’s calculated through a formula
Can Imacimus send the RS-485 info to other systems like the PLC?
No, they cannot send the information to other systems. Imacimus 10 comes as a closed team. Other teams have connectivity options. AMIC7
Why is it important to condition the equipment before calibration?
To rehydrate the sensor and balance them all previous to measurement. Leave the sensor immersed in the conditioning solution for a limited time.
How long does conditioning take?
Conditioning time depends on the equipment use. With a daily use, it’s recommended to condition for 20 to 30 minutes. With a sporadic use (weekly, monthly) we recommend between 2 and 3 hours of conditioning before calibration.
What if I leave more/less than the time indicated by the probe?
According to the first conditioning period, what happens if I leave more/less than the indicated time to the probe?
It is advisable to condition the probe a maximum of 8h for the first conditioning. Shorter time (<4h, first use) may not have the optimal state for calibration of any sensor. It is not advisable to exceed 24h of conditioning. [/av_toggle] [av_toggle title='Sensor time in the conditioning solution?' tags='' custom_id='' av_uid='av-lf2j9894' sc_version='1.0'] The first time you use Imacimus, it must be conditioned a minimum of 8 hours, from that time, does not bring benefit or negative action to the electrodes. Remember:
The necessary conditioning time varies depending on the use given to the equipment. With a daily use, it is recommended to condition between 20 and 30 minutes. With sporadic use (weekly or monthly), it is recommended to condition between 2 and 3 hours before calibrating.
Does the sample need to be isolated at the bottom in any way to facilitate the measurement?
No, the measurement is done directly. The color or turbidity don’t affect the results although a filtration is always recommended. The pH range is wide and a variation of it do not affect signifficantly between 4-9.
Conditioning solutions for use in seawater?
Water quality monitoring should be constant to prevent disease in organisms.
Which of the conditioning solutions is recommended to use in the multi ion probe for use in marine water?
In marine or salt water, if it exceeds 10 PPT, it is a specific solution. Below it, you can use mid-range.
Conditioning pH, lithium, fluoride, nitrite, bromide and perchlorate?
These sensors work individually, each sensor is conditioned in a 1000 ppm solution of the primary ion.
How is the Imacimus calibration?
Very simple and guided by our Software.
Please click on the following link to view the video tutorial: https://www.ntsensors.com/es/videotutorials/
How is calibration done?
Follow the steps indicated in the Users Guide. You can also take a look at this video about calibration: https://www.youtube.com/watch?v=MJXGownm5yE
How do I know the calibration is finished?
When the results in the screen show the symbol v. If calibration and mesurement has been done correctly, the value read must be 10mg/L. You must pay attention to a) do not cross standard solutions with others with higher values b) must leave the sensor immersed for a minute to obtain the electrode value.
When do I need to calibrate?
One calibration every day you are going to measure. It works for all the measurements / samples
How many samples can I measure with one calibration?
You can measure all necessary samples with a single calibration. However, a recalibration is recommended every 10-15 samples for the Standard 2 (you can do it manually or set alarm in our software).
Do we need to calibrate the equipment with an external supplier?
The equipment is factory verified.
The calibration of the system is usually done by the same user who takes the readings, as it is a simple process, and it only takes a few minutes. The equipment is similar to a pH measuring system, which, being double channel, allows to measure pH and ion.
Attached are instructions in electronic format (105_Imacimus2_UserGuide // 201_SingleIon_UserGuide).
In any case, if the technician who will employ you requires any doubt, you can contact our technical service through our website, and they would support in the use of the system or training.
When to rinse and dry?
During calibration only the pH electrode should be rinsed with DI water, not the multi ion probe, it is not necessary, since we always calibrate from lower to higher concentration. Always rinse with DI water after measuring a sample.
I get some parameters with "X!
If I left conditioning the 8h probe and when doing the first calibration I get some parameters with “X” to what is it?
Empty and clean the bottles in the case, dry them and refill them with new calibration liquid. If it persists, check sensor connectivity, and/or replace the sensor.
If an electrode fails constantly in calibration
If an electrode fails constantly in calibration, can it be related to any other sensor? Which one?
No. Sensors are and work independently.
In how many electrode calibrations is it exhausted?
In how many calibrations could one say that an electrode is exhausted?
There is no exact number. The calibration parameters indicate the state of the calibration over time/use. Depending on the type of sample, preservation and handling, as well as the type of electrode, will determine the need for electrode replacement.
Do waves, electromagnetism and static affect readings and/or calibration?
The equipment is insulated, although these waves can alter the results of the device. If yes, how far is it recommended keeping any apparatus? As far as possible to avoid distorted data.
There are many sensors that are not calibrating, what can I do?
Do an extra cnditioning fr 4-8 hours; renew all the standards and calibrate again. If it’s still not working, the sensors must be renewed.
What is the percentage or margin of error when calibrating?
The system allows some margins for the acceptance of calibration based on mathematical values.
How do I reclaibrate?
Take a look at our instructions manual: Advanced User guide.
When do I re-caliber?
Daily calibration, before using the equipment. Re-calibration every 10–15 samples, or if they have passed more than 2h of calibration. (Re-calibration is depending on the accuracy that is required, more or less frequency).
SAP Calibration
What if the equipment I purchased for sap measurement, but caliber with standard solutions already included in the equipment?
The ranges included with the equipment serve for a wide range of samples, and allow data extrapolation. That is, they can measure sap samples with the initial solutions. Alternatively, calibrators are manufactured that are closer to specific sample ranges, such as sap and others, to improve accuracy.
Can Imacimus results be compared with laboratories results?
Can Imacimus results be compared with laboratories results? Is there any study/document with comparative related information?
Imacimus is a lab equipment, based on electrochemistry, so the results are comparable to any laboratory measurements. Electrochemical instruments offer quantitative determination on the ionic species (parameters), with high accuracy. It also depends on how the user takes care/manages the equipment.
If the sample is in within the same conditions, the Imacimus results are within the same basis as any other lab report. I’ve attached a technical report showing related comparative information of Imacimus vs other labs, that was held a few years ago by an independent party.
Can two or more of the electrodes be use in the same sample solution for simultaneous measurements?
Yes, of course. They share a common reference electrode.
Is Imacimus suitable for continous detection?
Probes are not made to be left immersed in the sample solution for a long time. It’s recommeded to retract the probe or use a flow cell / or automatic system. AMIC7
Can probes be submerged for a long time?
No, the probes are not designed to be left submerged for a long period, as they must be recalibrated often and it affects its lifespam. If a sensor is in a sample, it is working continously whether you are reading the sample or not. They are neither designed to be fully submerged; there’s a mark in the Probe indicating the max level of submersion.
What’s the range of measurement?
Depending on your goal, we have calibration solutions of low, medium and high range (mor information at the available calibration solutions PDF). If needed, we can also create specific solutions adjusted to your needs. Medium range is usually coming with the equipment, and it works for wide range of samples.
Do I need any extra solution for the analysis?
No, you don’t need anything else than what’s provided in the measurement kit.
If probes can’t be continuously monitoring a sample, how can I do it then?
There are 3 different options to continuos monitoring available:
1) Collect all the measurements of the day (or per week), and try to get the measurements all together (it takes around a 1 minute per sample when calibrated)
2) Use the probes in a measurement cell/ recipient. Just make sure the probes are left in the air between measurements, and use a small pumping system to fill in the sample.
3) Move on to an automatic system (see our catalogue and contact us for more information).
Can I leave the probe waiting in the last analysed sample?
Never. It must be retrieved immediately and rinsed with DI water.
Does the sample need to be isolated at the bottom in any way to facilitate the measurement?
No, the measurement is done directly. The color or turbidity don’t affect the results, although a filtration is always recommended. The pH range is wide and a variation of it do not affect significantly between 4-9.
What is the minimum non volume of the non-diluted solution to be measured?
It depends on the sensor model, usually a drop is the minimum quantity. The tip surface must be in contact with the sample.
For standard Mini 2.5 it is around 100uL and for the Mini4.6/Single Ion of 12 mm the minimum is around 5 mL.
What is the maximum temperature range of the sample ?
What is the maximum temperature range of the sample to obtain real values that do not damage the sensors?
Range of use 5-35ºC. Samples should be at the same temperature as calibration solutions. Ideally for serious sensitivity at room temperature (20-25ºC)
Over your working temperature range (5-50degC)...
Over your working temperature range (5-50degC) does the temperature of the sample solution affect the concentration measurement and, if so, do you compensate for it in the circuit board?
In ISE measurement temperature is a factor to taken into account. There is no compensation of temperature on ISE sensors. Usually measurements must be taken at similar temperature as calibration.
Can I read the Single Ion probe simultaneously with Imacimus?
Yes, the meter can be used both with Single Ion probe and Multi Ion probe, although it must be done separately.
Is your equipment useful for heavy metal parameter detection?
Our systems are not suitable for such parameters, since the required concentration is usually below the 0.1 ppm and the ion-selective electrodes do not work properly in that lower range.
What is meant by Interference in ISE measurements?
Unfortunately, most ion-selective membranes are not entirely specific for the designated ion but also allow the passage of some other ions to a greater or lesser extent. This increases the charge on the membrane above that which is due solely to the detected ion and causes a spuriously high measurement. This phenomenon is known as interference and the extent of this interference is expressed as the Selectivity Coefficient.
Conductivity and hardness values are not displayed...
When I get an “X” in the calibration and then I make a measurement the parameter marked with “X” does not give the reading, however, the values of Conductivity and hardness are not shown, indirect measurement parameters do not act independently?
How do they relate to direct parameters?
Conductivity and hardness have no sensors. These parameters are calculated mathematically. If any sensor/ion fails, it is not possible to get the value. Direct parameters can be obtained by using the relevant mathematical formulas.
What’s the selectivity coefficient?
The selectivity coefficient is a numerical measure of how well the membrane can discriminate against the interfering ion.
To put this in perspective, if an electrode has equivalent responses to the two ions, then kij = 1.0. As you can see from the equation, (Emeas=const+0.05916zlog(Ai+kijAzizjj)) the smaller the kij values, the less impact the interfering ion will have on the measured potential.
When kij values are less than 1, the ISE is more responsive to the analysed ion and when kij values are greater than 1, the ISE is more responsive to the interfering ion. For example, a kij value of 0.01 means that the electrode is 100 times more responsive to ion i over j.
Is the Ionic strength noticeable in the measured samples?
The combination of multiion solutions makes negligible the ionic strengh differences usually found in samples.
How is water hardness measured?
Water Hardness is by definition the Calcium and Magnesium ions measurement. With the readings of total calcium and magnesium ions in the sample, the water hardness is calculated through a mathematical formulae.
How are the standards?
We manufacture multiION standards in order to be able to calibrate up to seven IONs simultaneously. You could calibrate individually each ion with its single standard, but it is not so common at least for agro field. Lab uses can require specific standards, so the use of single ion standards would make more sense.
What’s the necessary liquids volume to calibrate?
Use 15-20ml for up to 3 calibrations.
What’s the useful life of a calibration solution?
15 ml / change every 3 calibrations
125mL bottle -> a minimum of 25 calibrations –> 625 samples
250mL bottle -> a minimum of 50 calibrations –> 1250 samples
How many calibrations can I do with a 250ml bottle
t’s calculated to last for 60 calibrations approximately.
Is the meter compatible with Mac/Apple?
The software provided for the imacimus is only executable on Windows based systems. To run in IOS, you will be prompted to install a windows emulator, and then run the imacimus software in such environment.
Can I upload data directly to the cloud?
No, data can be exported from the software via a .csv file; even though you can upload that file manually to a cloud if you want to.
Is your equipment useful for heavy metal parameter detection?
Our systems are not suitable for such parameters, since the required concentration is usually below the 0.1 ppm and the ion-selective electrodes do not work properly in that lower range.
I transfer the data from one pc to another?
When the software is downloaded is it mandatory to do the measurements always using the same laptop or can I transfer the data from one pc to another?
You can download the software as many times as you need using the Serial Number of your meter. The data is stored locally, though you can transfer it to a .csv file and move it freely.
Is it possible to use the meter in different computers simultaneously?
Is it possible to use the meter in different computers simultaneously? If positive, is a calibration necessary in both of them?
The first time you must calibrate in each computer you use, and after that each system will save a different calibration ; the last one in that specific computer. So, we highly recommend to calibrate every time you use a different computer.
Can the data automatically be extracted from the software (is it open)?
The customer is not interested in using Excel (old fashioned) and he would like to have the data available in his general software system..
Currently, the data comes automatically on the software. From the same screen with the results results can be extracted (by one click) on CSV or Excel format.
Can graphs automatically be made?
Graphs are only in continuos mode. Not made automatically in the batch measurement.
Where is the data stored?
The data is stored in the computer.
What’s the technique based on?
The IMACIMUS is a MultiION meter based on electrochemistry technique, Nernst Law, with the innovation of a patented technology of carbon nanotubes inside.
It is a quantitative instrument with lab accuracy, and like any other laboratory technique, it depends on the user. Each electrode has got detection limits. For more info related to that please take a look on the specifications datasheets.
The electrodes are fungible, and they are spare parts that must be replaced by the user time to time.
Can I integrate the device on our PLC/PCB board?
Yes it can be integrated in your own PCB, although the output for the sensors is analogic, mV data. You need a high impedance input (similar to the pH electrodes) to readout the signal of the ISE.
Digital: USB/UART
Analogic: Signal 4-20mA
Open Source Plataform Arduino C+
We have a module that is a multiparametric meter, with output connectivity using Rx, Tx communication for developers with Arduino or similar. This can be used as an alternative, or you can adapt your PCB to properly read ISE.
How to transfer data from sensors to PLC device via USB?
Output from AMIC system is done physically through an USB connector.
Its must have the first configuration be made through the provided Windows software. Once initiated, the communication can be established through the following communication protocol.
• Output usb protocol (Universal Asynchronous Receiver-Transmitter, UART)
• Transmission speed or rate, baud (9600)
• Parities (8 data bits, no parity, one stop bit)
4 plots are sent corresponding to: latest multion calibration, measure, pH calibration
and pH measure.
Any third party device can link to the equipment using the previous communication protocol in order to operate the system.
Develop Partners
Our company manufactures electrodes and meters. Our meters process the analogic signal from the sensors, to a digital output.
We have a research model that is directly connected to an OPEN SOURCE PLATAFORM in order to read the mV output from the sensor. Our meters are multiparametric, up to 7 different parameters simultaneously.
The NTx DEVELOP series equipment are based on an internal programming that allows to obtain the raw signal data from the sensors in digital format (mV), through Rx, Tx, GND communication. One of the typical applications is to couple Arduino equipment, which interrogates the meter when you want to get the reading of the sensors.
