Electrolyte analyzer principle of work

Electrolyte analyzer test object is diverse, whether serum or whole blood or plasma can, urine sample, dialysis fluid samples from even liquid can also directly measure the hydration, is the function is very powerful a medical instrument. Electrolyte analyzer can detect the inorganic salt ions, sample calcium ions tiny material, etc.
Now let's introduce electrolyte analyzer principle of work:
Electrolyte analyzer have use ion selective electrode method to achieve precise measurement of the testing. The apparatus are six electrodes: sodium, potassium and chlorine, calcium ions, lithium and CST electrode. Each electrode has a ion selective film, will be measured and samples corresponding ion responses, the membrane is a ion exchanger, and ionic charge reaction and change the membrane potential, it can detect the liquid, samples and membrane potential between. Film on both sides of the two electric potential tested value will produce the current, samples, reference electrode, reference electrode liquid form "loop" side, membrane, internal electrodes liquid, internal electrodes are the other side.
Internal electrodes fluid and sample the difference between the concentration of the ions will work on both sides of the film electrode in create electrochemical voltage, through high voltage of the conductance of the internal electrodes to lead to the amplifier, reference electrode also led to the location of the amplifier. Through the test a known precisely the concentration of the ions standard solution for calibration curve, and the test sample the concentration of the ions.
Only provides the electrolyte analyzer perlong medical treatment for users to serve as reference.
