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). Automated Electrolytes are measured using ion-selective electrodes (ISE) and colorimetric and photometric techniques. Most electrolyte analyzers are capable of high throughput ranging from 400 to 2400 tests per hour. The CLS016 product measures various combinations of sodium, potassium, Ionized Calcium, Lithium, pH Bicarbonate, and Chloride in whole blood, serum, plasma, and urine.
