Analysis in Spirulina cultivations, Nitrogen and PH

ANALYSIS FOR SPIRULINA CULTIVATIONS

At NTSensors, we provide a cost effective solution for the analysis in Spirulina platensis growing medium at large scale production.
The commercial mass-production of Spirulina has gained worldwide attention for its use in human food supplements, animal feed and pharmaceuticals. Spirulina contains up to its 70% weight in protein, high amounts of essential fatty acids, essential amino acids, minerals, vitamins (such as B12), antioxidants (such as phycobiliproteins and carotenoids) and polysaccharides.

Production of Spirulina with reduced costs is necessary when considering large-scale cultivation for industrial purposes. The growth of Spirulina and the composition of the biomass produced depend on many factors, the most important of which are nutrient availability, temperature and light. The cost of nutrients is considered the second most important factor which influences the cost of Spirulina bio mass production, only after labor. Therefore, it is of special economic interest to know the concentrations of the nutrients available in real-time.

The most important nutrients in Spirulina growing medium are Sodium, Potassium, Phosphate, Nitrate, Sulfate, Chloride, Magnesium, Calcium, and Amonium.

In particular, the levels of Nitrate and Amonia are of critical importance in the large scale production of Spirulina platensis. Several studies have drawn attention to the importance of monitoring the concentration of nitrogen in phyto-plankton cultures, because it may modify the metabolic activities and consequently, the composition and nutritional value of microalgae and cianobacteries, which is important to consider in aquaculture practices.
Other important nutrients, such as Potassium, Calcium, Sodium, Chloride and Magnesium are part of the Spirulina organs and contribute in different key processes for the organism growth. The right balance of all these nutrients provide the right medium for the optimal growth of Spirulina platensis.

PH analysis is also a key aspect of analysis in Spirulina cultivations growing medium, as pH determines the optimum growth of Spirulina platensis cianobacteria and at the same time prevents the presence of pests. Spirulina grows in alcaline pHs between 9,3 and 10,5. This pH naturally limits the growth of pests, so that no phytosanitary treatment for pest control (such as herbicides or pesticides) is required.

NTSensors solutions for the analysis of Spirulina growing medium

NTSensors Imacimus10 ISE meter multi-ion equipment is the most complete solution for a quick, inexpensive and reliable measurement of up to 10 parameters in Spiruline growing medium in real time. With Imacimus10 equipment you can measure 7 nutrients together with pH, conductivity and water hardness. For the analysis in Spirulina cultivations medium we recommend to measure these 7 nutrients: Nitrate, Ammonium, Calcium, Chloride, Potassium, Sodium and Magnesium.

Imacimus5 ISE meter kit allows the simultaneous analysis of four nutriens and pH. An apropiate ISE kit for Spirulina growing medium analysis would be Nitrate, Ammonium, Potassium and Magnesium analysis.
For the analysis of a unique ion and pH, NTSensors offers several ion meter solutions, such as Nitrate and pH meter or Ammonium and pH meter.

With a measuring range of 1 to 10.000 ppm, NTSensors Imacimus10, Imacimus5 and ISE meters provide a fast and reliable solution for the measurement of the key nutrients in commercial mass-production of Spirulina.

Chloride for ion selective electrode

 

The Chloride Ion Selective Electrode is a crucial tool for measuring chloride ion concentrations and activities in aqueous solutions. Its selectivity, affordability, and ease of use make it a popular choice for a variety of applications in different fields, including environmental monitoring, food and beverage production, and pharmaceuticals. With proper care and attention to interferences, it can provide accurate and reliable results for scientific research and industrial processes.


The Chloride Ion Selective Electrode is a scientific instrument that is used to measure the concentration and activity of chloride ions in aqueous solutions. Chloride ions are found in many areas of scientific research and industrial applications, including environmental monitoring, food and beverage production, and pharmaceuticals.

Ion selective electrodes work by generating a voltage in response to the presence of a specific ion in a sample solution. This voltage is proportional to the concentration of the ion being measured and can be used to determine the ion activity.

Compared to other analytical techniques, ISEs are relatively inexpensive and easy to operate, making them a popular choice for many applications.

It is important to note that while the Chloride Ion Selective Electrode is highly selective to chloride ions, it can be affected by interference from other ions present in the sample solution. Careful consideration must be given to sample preparation and analysis conditions to minimize these interferences and obtain accurate results.

In environmental monitoring, the Chloride Ion Selective Electrode is widely used to determine the chloride ion concentration in water, soil, and other environmental matrices. In the food and beverage industry, it is used to monitor the chloride ion concentration in products such as sauces, salad dressings, and mayonnaise. The Chloride Ion Selective Electrode is also used in the pharmaceutical industry to determine the concentration of chloride ions in drug formulations.

Ammonia Ion Selective Electrodes: A Comprehensive Guide

Ammonia Ion Selective Electrodes

A Comprehensive Guide

Ammonia ion selective electrodes (ISEs) are analytical tools used to measure the concentration of ammonia ions in aqueous solutions. These electrodes are commonly used in environmental monitoring, wastewater treatment, and other applications where accurate measurement of ammonia levels is critical.

Nota

With its ability to selectively detect ions and provide precise measurements, an ion-selective electrode is a must-have for any laboratory or research facility.

Ammonia ISEs work by using a membrane that is selective to ammonia ions. When the electrode is placed in a solution containing ammonia, the ions will diffuse through the membrane and interact with the sensing element inside the electrode. This interaction produces a change in the electrode’s potential, which can be measured and used to determine the concentration of ammonia in the solution.

There are several factors that can affect the accuracy and reliability of ammonium ion selective electrodes measurements. These include the pH of the solution, the presence of interfering ions, and the condition of the electrode itself. To ensure accurate results, it is important to calibrate the electrode regularly and to follow proper measurement procedures.

Nota

If you are in need of accurate and reliable measurements of specific ions in a solution, an ion-selective electrode is the perfect tool for you.

In addition to their use in analytical applications, ammonia ISEs can also be used for process control. For example, they can be used to monitor and control the levels of ammonia in wastewater treatment plants or aquaculture systems.

Overall, ammonia ion selective electrodes are powerful tools for measuring ammonia levels in aqueous solutions. By following best practices for measurement and calibration, you can ensure accurate and reliable results.

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.
