Electrolyte analyzers are instruments used to detect potassium, sodium, chloride, calcium and lithium ions from a sample. Samples can be whole blood, serum, plasma, urine, dialysate, and hydration fluid.
Electrolyte analyzers are indispensable in clinical tests, in which it mainly tests the maintenance of human blood. The balance of osmotic pressure in body fluids, testing and detection of ions is important in surgery, burns, diarrhea, acute myocardial infarction, etc. The instrument has high precision and accuracy, and the results of any sample are accurate, reliable, fast, and very simple to operate. Therefore, ion detection is an essential general equipment for hospitals at all levels.
Electrolyte analyzers use the ion-selective electrode measurement method to achieve accurate detection. There are six electrodes on the instrument: sodium, potassium, chloride, ionized calcium, lithium and reference electrodes. Each electrode has an ion-selective membrane, which will be The corresponding ions in the test sample react. The membrane is an ion exchanger, which reacts with the ion charge to change the membrane potential, and the potential between the liquid, the sample and the membrane can be detected. The difference between the two potentials detected on both sides of the membrane will generate Current, sample, reference electrode, reference electrode fluid form one side of the "loop", membrane, internal electrode fluid, and internal electrode on the other side.
