Electrolyte Analyzer

Electrolyte analyzers measure electrolyte levels in the human body to detect metabolic imbalances and measure renal and cardiac function. The electrolytes measured include sodium (Na+), potassium (K+), chloride (Cl-) and bicarbonate (HCO3- or CO2). Electrolyte analyzers are used in hospital and reference laboratories, and also point of care settings. Most electrolyte analyzers use blood plasma, serum, or urine samples; some analyzers can use whole blood (for faster turnaround time) and cerebrospinal fluid (CSF).

The most common methods of analysis are – Flame Emission Photometry (FEP) and Ion Selective Electrode (ISE). Flame Photometry can be used to measure Na+, K+ and Li+. It provides an indirect measurement, while ISE methods offer direct measurements. Most analyzers use ISE technology to make electrolyte measurements.
