The first, electrolyte analyzer membrane electrode and tube electrode difference
There are a lot of manufacturers of electrolyte analyzers are still using the tube electrode. Tube electrodes are very unstable because of high impedance and relatively large influence by temperature and magnetic field. Electrodes are housed in an all-aluminum alloy electrode shielding box, and the instrument has to have a special grounding, the instrument can be detected. The tube electrodes also have to be maintained routinely with an electrode care solution. Membrane electrodes do not have the above problems. 1906 by Cremer invented the H ion sensitive glass tube electrode, glass tube electrodes are gradually commercialized, membrane electrodes are developed after the 1960s and 1970s.
The second electrolyte analyzer side-drive sampling and the traditional wrench sampling method of comparison
The traditional wrench sampling is a backward sampling method, because if the front wrench sampling needle, sampling needle residual serum and other liquids will be splashed with the shaking, may be splashed on the operating table or the operator's hands or clothes, both unhygienic and unsafe, not to mention the environmental protection. General high-grade instrument injection needle are used in automatic telescopic reset (closed) type. Side-driven automatic reset type sampling, in the side of the instrument, the sample serum and other samples from the body of the medical staff farther, health and safety, to protect the operator's health. Moreover, the waste liquid directly slides down to the waste liquid bottle, which is more environmentally friendly. At the same time, side-drive sampling is more intuitive, so it is easy to operate.
The third, distribution valve and solenoid valve comparison
There are many electrolyte analyzer manufacturers use solenoid valves to achieve the control of the flow path, the result is that the flow path is particularly complex, the flow path is also particularly long, the use of solenoid valves in large numbers. Therefore, the flow path is clogged with many faults, and maintenance is also frequent. Photoelectric positioning liquid dispensing valve, with a high degree of integration, a dispensing valve can control four flow paths, while the same four flow path control requires two to four solenoid valves. So the distribution valve greatly simplifies the flow path, reduce the failure rate.
The fourth, electrolyte analyzer automatic deproteinization and manual deproteinization comparison
It is obvious that automatic deproteinization without human intervention, high degree of intelligence. If the technology can be achieved, who still manually remove protein? Some manufacturers in the flow path cleaning, even played the original wave theory, in the flow path so fine pipeline can see the wave?
The fifth, electrolyte analyzer touch screen and the difference between the keyboard method
In general, their focus is different, the keyboard focuses on input documents, focusing on human-computer interaction, while the touch screen focus on entertainment. If you are given a computer, and when you use the computer to edit text, the keyboard is broken, you will feel that the keyboard is more important than the mouse. Electrolyte analyzer is a medical device, it is a testing and analyzing instrument, when the instrument is working, it needs human intervention and input instructions. So the keyboard approach is more appropriate, rather than to pursue fashion and mislead consumers.
Sixth, USB communication interface and RS-232 communication interface
Modern computers have been gradually eliminated RS-232 port, the use of a unified universal interface USB interface to achieve the peripheral and the computer data transfer between the USB interface supports the device's Plug and Play and hot-swappable function. Convenient query, editing, stay at the bottom of any printout. Data transmission is more convenient, more suitable for major hospitals.
From the above comparative analysis of the performance of electrolyte analyzers, we can clearly see the use of electrolyte analyzers what way to work is the best. The above information is for reference only!
