Difference Between Electrolyte Analyzer and Blood Gas Analyzer

Blood gas analyzers and electrolyte analyzers confuse a lot of people. What are differences between electrolyte analyzer and blood gas analyzer? We can be analyzed from the working principle and the basic structure of the electrolyte analyzer, blood gas analyzer look at, as follows below:
The working principle and the basic structure of the blood gas analyzer
How it works: suction of tested blood samples in the piping system. Measurement capillary into the sample chamber, the measurement on the wall of the capillary opening has four holes, hole PH, PCO2, and PO2 three measuring electrode and a reference electrode inserted. Among them, PH measuring electrode and the pH reference electrode composed of pH measurement system. The blood sample into the sample chamber after the piping system of the measuring tube is stopped pumping, the sample at the same time the sensed by the four electrodes. Electrodes produce an electrical signal corresponding to the PH, PCO2 and PO2 three parameters. These electrical signals are sent to the microprocessor after the analog-to-digital converter respectively enlarged. Processing of changes in blood flow by the computer processing system, after the operation, and then are sent to the respective display unit display or printer to print out the measurement results, measured in the detection chamber finished samples were flushing fluid discharged into the waste bottle.
The basic structure of the blood gas analyzer: an electrode system (the core part) (mainly including ion electrode and voltammetric sensor), the piping system and the circuit system.
The electrolyte analyzer works and the basic structure
It works: electrolyte analyzer multi-ion selective electrode method, this medical equipment is easy to operate, low cost, quickly and accurately trace and continuous automatic determination of benefits. The work can be divided into wet and dry.
The basic structure: Wet (​​electrode system <includes information indicating electrode and the reference electrode, the reference electrode is typically silver / silver chloride electrode> is its core portion) comprises: ion selective electrode, the reference electrode, the analysis box, the measurement circuit, a control circuit, the drive electrodes and the monitor.
A class of both dry-electrolyte analyzer electrolyte dry chemical assay is based on reflectance spectrophotometry, and the other is based on the method of ion-selective electrodes.
