Which Types of Ion Selective Electrode to Use?

An Ion Selective Electrode (ISE) is a type of electrode that is sensitive to a specific ion in a solution. ISEs are used in a variety of applications, including electrochemistry, sensors, and analytical instruments.

An ion-selective electrode (ISE) is a sensor that responds to a particular ion in solution by producing an electrical potential. This potential is proportional to the concentration of the target ion. ISEs are used in many different applications, including environmental monitoring, clinical diagnosis, and industrial process control.

There are three main types of ISEs: potentiometric, amperometric, and conductimetric. Each one has its own advantages and disadvantages.

There are many different types of ion selective electrode (ISE) available on our store.


Types of Ion Selective Electrode & applications

Potentiometric ISE measure the potential difference between two electrodes as a function of concentration.
Potentiometric ISE applications include pH measurement, ionic strength measurements, and metal analysis.

Amperometric ISE use a current flow to determine the concentration of ions in solution.
Amperometric ISE applications include glucose monitoring, DNA sequencing, and protein detection.

Conductimetric ISE use a voltage drop across a resistor to determine the concentration of the ions in solution.
Conductimetric ISE applications include heavy metals testing, drug screening, and environmental monitoring.

  1. It measures nitrogen levels with an ISE nitrogen sensor. A nitrogen sensor measures the nitrogen level in its solution. You can use this data to determine whether you need to add more fertilizer or not.
  2. Monitors nitrate levels with a nitrate ISE sensor. A nitrate sensor monitors nitrate levels in its solution. This allows you to see how much nitrate is available in your solution.
  3. Detects ammonia levels with an ammonium ISE sensor. The ammonia sensor detects ammonium levels in water. It will let you know when the level is too high. You can adjust the pH of your solution to reduce ammonia levels.
  4. Check pH levels with an ISE pH sensor. A pH sensor is a small device that connects to the sample. It measures the pH of your water and checks data. This allows you to see how your plants are doing.

Water Quality Monitor

A pH sensor will alert you when the pH level drops below 5.5 or rises above 7.0. If you notice a sudden drop in pH levels, you should check your water quality immediately. You can also use an inline pH sensor to measure the pH of your water every day.

NT Sensors celebrates 10 years of business experience in the electrochemical market

The company makes a satisfactory balance of its business trajectory focusing on the current moment where future prospects are more optimistic than ever and the company is fully consolidated in the market. NT Sensors, held last Friday, November 30, the commemorative act of its tenth year anniversary. Their success com from constant development of firm values ​​and a hardworking, innovative and ambitious team. The event was held at the company’s facilities located in El Catllar, Tarragona and was attended by NT Sensors’ employees, board of directors, and the media. Cristina Cid, co-founder of the company welcomed the attendees and made a brief review of the company’s history and journey throughout these past 10 years. She also explained that the company’s strategy, as of now, goes through a clear commitment to marketing and communication. In this line, two projects have been presented that will help raise awareness and create the NT Sensors brand. On its 10th anniversary, the company plays on the occasion to change its corporate image and reflect its achievements, values, innovative solutions and the essence of the company. A new image that marks the beginning of a new stage. NT Sensors company is in constant evolution in all senses: economic results, human team, values, internationalization of the company and settlement in the market. The process has been completed with the launch of a new corporate website, which allows access to a more clear, concise, and accessible content from all types of devices. This new identity reflects the firm’s mission, which is to bring chemistry closer to all fields that require analysis of aqueous samples, offering laboratory results at an affordable cost and with the most innovative technology. How she explains, Dr. Cid “This image change goes far beyond the purely visual. It transmits all the experience and knowledge we have gained during these years, as well as the values ​​of excellence, criteria and technological innovation that defines us “. She adds “After the growth we have experienced in recent years, our brand had to be renewed to help us transmit the values ​​of NT Sensors, an innovative, reliable and young company that offers tailored solutions to suit all types of customers, which day by day they trust us, and they have helped us grow.” Finally, the event ended with a snack where participants could enjoy a relaxed atmosphere by closing the act with a toast with cava for the future of the company. NT SENSORS: 10 YEARS OF LEARNING NT Sensors was founded in 2008 a Spin Off of the University Rovira i Virgili, starting the economic activity just at the beginning of the crisis in which many companies were forced to suspend their activities. Despite going out to the market that year, the company has a considerable turnover that augurs good prospects for the future. The company was born under the umbrella of the URV and with a patented nanotechnology formula applied to its products as a differential feature. NT Sensors offers high precision analysis solutions on the composition of aqueous samples. With this premise, develops high quality products at an affordable price thanks to the unique formula of NT Sensors. Ten years after its incorporation NT Sensors has clients and distributors in five continents. The project started with only three people on staff and making a clear commitment to research and development. Today, after ten years of activity, the company has gone through different stages and currently its market share exceeds € 200,000 in sales and it is expected to triple this amount in the coming years. Currently the company has a portfolio of clients spread around the world, including universities such as the University of Almeria, Hardvard and collaborations with leading organizations and companies such as NASA and Friedrich-Alexander-Universität Erlangen-Nürnberg FAU. NT Sensors wants to further internationalize its brand and take it to all corners of the world. In the coming years, the company expects to grow in this sense, which will allow them to exponentially increase sales. On the occasion of its 10th anniversary, NT Sensors has submitted an interim report with the data corresponding to the last years’ activity, in which it is reflected that the turnover of NT Sensors has registered an increase of 40% compared to 2015. This data is maintained for other years in which the company has managed to establish a stable growth, thanks to the commitment to a strategy in marketing and communication, as well as an excellent customer service.


Excellence in crops: precision agriculture

Precision agriculture is a relatively new concept. It was born in the USA at the beginning of the 80s, but its importance grows exponentially in recent years with the arrival of new technologies (sensors, GPS, drones …). Field and crops are dynamic and are constantly changing, therefore it is necessary to analyze and understand all those variations and particularities of the environment in order to be able to provide the exact inputs for crop optimization.

The application of the most innovative technology, in all fields of agriculture, allows us to obtain the necessary information to understand the variations of soil and crops. To be able to understand the variability of the productivity of agricultural systems we must analyze two concepts: The spatial and temporal variability.

The spatial heterogeneity is caused by different environmental factors, among which, is the soil (texture, depth, nitrogen content phosphorus and potassium), weeds, and diseases. In this case we can use nutrient analyzers like IMACIMUS to know the composition of the soil, the sap or the nutrients present in irrigation water.

In contrast, the temporal variation is mainly related to differences in climatic conditions between years (hail, drought, rain, etc.), as well as, to management and cultivation practices.

Successful application of Precision Agriculture practices increases the efficiency of production processes and reduces costs while reducing pollution

Precision agriculture consists of four phases, the first is the acquisition of data, then the analysis of this data and decision making in relation to the information obtained. These actions can be both preventive (eg, anticipating pests and diseases) or management (eg knowing how much and when to irrigate with consequent savings) thanks to forecasts and measurements.
The fourth phase is performance monitoring. The fact of evaluating the production, our actions and the final performance, allows us to correct course and know our successes. This is possible thanks to the continuous monitoring we have of the crop and thus measure the immediate and long-term effect of our actions. The ability to store information allows us to compare campaigns.

Imacimus Multi Ion, nutrient analyzer

In short, precision agriculture implies a cyclical system of data collection and GIS (Geographic Information Systems) have a preponderant role in the integration, interpretation and analysis of the available information. The information collected through the new technologies allows us to evaluate with greater precision the optimum density of sowing.

Through sensors we can estimate the appropriate amount of fertilizer or other necessary inputs, and more accurately predict the yield and crop production. With IMACIMUS it is going to be a simple and fast task.

IMACIMUS is the fastest and most reliable nutrient analyzer on the market thanks to its formula based on nanotechnology patented by NT Sensors. Precision agriculture is fundamental to the sustainable development of the agriculture sector. With these new production systems, we will be able to guarantee a sufficient and sustainable agricultural production.
