First, the difference between membrane electrode and tube electrode of electrolyte analyzer
Many manufacturers still use tube electrode in electrolyte analyzer. The tube electrode is very unstable because of its high impedance and great influence by temperature and magnetic field. The electrodes are all placed in the all-aluminum alloy electrode shielding box, and the instrument can only be tested if it has a special grounding. Moreover, the tube electrode has to use an electrode care solution for daily maintenance. While that membrane electrode doe not have the above problems. In 196, Cremer invented the glass tube electrode sensitive to H ions, and the glass tube electrode was gradually commercialized. The membrane electrode was developed after the sixties and seventies.
second, comparison between side-drive injection of electrolyte analyzer and traditional wrench injection method
traditional wrench injection method is a backward injection method, because if the injection needle is pulled in front, the residual liquid such as serum on the injection needle will splash out with shaking, which may splash on the operation table, the operator's hands or clothes, which is neither hygienic nor safe, nor environmentally friendly. Generally, the injection needle of high-grade instruments adopts automatic telescopic reset (closed) type. Side-drive automatic reset sampling, at the side of the instrument, the sample serum is far away from the health of medical staff, which is hygienic and safe and protects the health of operators. Moreover, the waste liquid directly slides into the waste liquid bottle, which is more environmentally friendly. At the same time, side-drive injection is intuitive, so the operation is convenient.
Third, comparison between distribution valve and solenoid valve
Many electrolyte analyzer manufacturers use solenoid valves to control the flow path, resulting in a particularly complicated and long flow path, and a large number of solenoid valves are used. Therefore, there are many faults in flow path blockage and frequent maintenance. Photoelectric positioning liquid distribution valve has a high degree of integration. One distribution valve can control four flow paths, and the same four flow paths control requires two to four electromagnetic valves. Therefore, the distribution valve greatly simplifies the flow path and reduces the failure rate.
fourth, the automatic deproteinization of electrolyte analyzer is compared with manual deproteinization
It is obvious that automatic deproteinization does not require manual intervention and has a high degree of intelligence. If the technology can be achieved, who will remove the protein? Some manufacturers have even created an original wave theory in the flow path cleaning. Can you see waves in such a thin pipeline?
Fifth, the difference between touch screen and keyboard of electrolyte analyzer
Generally speaking, their emphases are different. Keyboard focuses on inputting documents and human-computer interaction, while touch screen focuses on entertainment. If you are given a computer, and the keyboard is broken when you edit text with the computer, you will feel that the keyboard is more important than the mouse. Electrolyte analyzer is a medical equipment and a detection and analysis instrument. When the instrument works, it needs human intervention and input instructions. Therefore, the keyboard method is more appropriate, not to pursue fashion and mislead consumers.
sixth, USB communication interface and RS-232 communication interface
Modern computers have gradually eliminated RS-232 port, and used USB interface to realize data transmission between peripherals and computers. USB interface supports plug-and-play and hot-plug functions of devices. It is convenient to query, edit and print at will. Data transmission is more convenient and more suitable for major hospitals.
from the comparative analysis of the performance of the above electrolyte analyzer, we can clearly see which way is the best to work with the electrolyte analyzer. The above information is for reference only!
