1.Brief Introduction of blood electrolyte analyzer
Electrolyte analyzer is used to test potassium ion, sodium ion, chlorine ion, calcium ion (PH) from samples. Samples can be whole blood, serum, plasma, urine, dialysate, and hydration liquid.
2．Application
The electrolyte analyzer Is indispensable in the clinical test, it is mainly in the clinical test to maintain human blood. testing and detecting ion is very important for Osmotic balance in the body fluids, for patients who need a lot of equilibrium rehydration in surgery, burns, diarrhea, acute myocardial. The instrument precision and accuracy is high. the results of any samples measured accurate, reliable, fast, and easy to operation. So, ion detection is essential universal equipment for hospitals at all levels.
3．Principle
Electrolyte analyzer with ion selective electrode method is used to achieve accurate detection. Six kinds of electrodes on the instrument: sodium, potassium, chloride, calcium ions, lithium and reference electrode. Each has an ion selective electrode membrane, which the tested sample and the corresponding ionic will react. Membrane is a ion exchanger, react with ionic charge and change the membrane potential.So it can detect the electric potential among liquid, the sample and membrane . On both sides of the membrane tested two potential difference value will generate an electric current. sample, and the reference electrode, reference electrode liquid constitute a “loop” side. membrane, internal electrode liquid, internal electrodes are on the other side.
Internal electrode ion concentration difference between fluid and samples will be at work on both sides of the membrane electrode electrochemical voltage, voltage through the high conductivity of the electrode to the internal amplifier, reference electrode is the same to the location of the amplifier. Through a precise detection of known concentration standard solution calibration curves, and detect ion concentration in the sample.
4,Operation
1）Start the machine into the system self-check, to test the major parts of the instrument detection function is normal or not, such as: motherboard, printers and liquid road testing instrument (done by fluid detector), the distribution valve and valve detector, etc.,It can be smart recognize fault, automatic prompt.
2)In the process ofactivation electrode, electrode activation timer function, accurate grasp the activation time, in order to improve the service life of the electrode, and ensure the stability of the electrode. Time is 30 minutes of the countdown.You can press the NO button directly exit activation electrode application.
3) Enter the main menu, first,calibrate the system, and it can automatically to calibrate the selection basis and the slope (also can choose to leave not calibration, repair and maintenance is convenient, but can not be directly measured serum specimens)
4) Choose quality control analysis, through 5 times quality control testing,It can be generated automatically and print quality report. Counted the average times of quality control of, standard deviation, coefficient of variation.
