Sodium ion-selective electrode is an effective method to measure the content of sodium ions in samples. Sodium ion-selective electrodes are also often used in on-line instruments, such as industrial on-line monitoring of sodium ion content.
Sodium ion selective electrode, with the advantages of simple measurement and accurate response, can be used with PH meter, ion meter and online sodium ion analyzer, and also used in the ion selective electrode detector of electrolyte analyzer and flow injection analyzer.
Application:
sodium ion in feed water treatment of power plant and steam power plant; sodium ion selective electrode method for sodium ions in mineral water, drinking water, surface water; sodium ion selective electrode method for sodium ions in tea, honey, feed, milk powder; sodium ion in saliva, serum, urine and other biological samples; sodium ion selective electrode method for content in ceramic raw materials.
