ISE Analyser

Ion-Selective Electrode (Electrolyte Analyser) 

The ISE Electrolyte Analyser uses electric potential difference to calculate concentrations of a given ion. When a sample is tested ions diffuse to ISE membrane, a potential difference between the measuring electrode and the reference electrode is recorded. Ion concentration is calculated using the “Nernst Formula”.

The ISE analyser can detect Ion concentrations in whole blood, serum, plasma, and urine samples in just 1 minute.


The system consists of automatic 2 point calibration and potential tracking for improved stability. An advanced washing programme for reduced cross contamination and prevention of system clogging. The ISE analyser uses minimal sample volume and is designed to reduce cost.
