3. Ion selective electrode based electrolyte analyser-Easylyte

Ion selective electrode The Easylyte analyser is based on ion selective electrode (ISE). The analyzer provides on accurate analysis of electrolytes in biological fluids including blood and urine.

The instrument measures sodium, potassium and chloride. In addition calcium/ph in biological fluids and also be measured using ISE technology. The flow through sodium and ph electrode contains glass tubing, specially formulated to be sensitive to sodium ions. The flow – through potassium and calcium electrodes emplay a plastic tube, incorporating neutral carrier ionophares

The flow –through chloride electrode includes a specially formulated plastic tube. The potential of each electrode is measured relative to fixed, stable voltage provided by the Ag/Agcl reference electrode. The relationship between the voltage developed and ion concentration as logarithm.
