Instran Online Potassium Meter
Continuous measurement of potassium concentration in water is possible!
Method - Ion Selective Electrode The analysis uses the known addition method (SKA). In this technique, two measurements are taken, and the difference between them, along with the slope obtained during calibration, is used to calculate the concentration. By performing both measurements, changes in the sample matrix are corrected, and the calculation uses the relative difference in mV rather than absolute values, allowing for the avoidance of external interference. An ion strength adjuster (ISA solution) is added to the sample to activate the electrode while simultaneously suppressing the effects of interfering components. Subsequently, the fluoride concentration is measured using the "Standard Known Addition Method (SKA)." This method is very simple and easy to implement. Additionally, because the SKA method corrects for electrode drift and variations in the sample matrix, stable results are obtained.
