Analysis of the principle of the action of pure water machine with biochemical instrument

　　Biochemical instrument with pure water machine action principle analysis ion exchange method is a spherical resin (ion exchange resin) to filter raw water, the water ions will be fixed on the resin ion exchange The two common ion exchange methods are hard water softening and deionization Hard water softening is mainly used in reverse osmosis (RO) treatment, the water hardness is reduced in a pre-procedure The globular resin inside the softener softens the water quality by exchanging two sodium ions for a calcium or magnesium ion
Ion exchange resins exchange cations for hydrogen ions and hydrogen oxygen root ions for anions, while cation exchange resins made of styrene and diethylene benzene containing sulfonate roots are exchanged for various cations (e.g Na, Ca2, Al3 plus) Similarly, anion-swapping resin made of styrene containing seasonal ammonium salts exchanges various anions (such as Cl-) that come into contact with hydrogen oxygenia The hydrogen ions released from the cation exchange resin are combined with the hydrogen-oxygen root ions released from the anion exchange resin to produce pure water
Yin and yang ion exchange resin can be packaged in different ion exchange beds, divided into so-called anion exchange bed and cation exchange bed It is also possible to mix the cation exchange resin with the anion exchange resin and place it in the same ion exchange bed In either form, when the resin and the charged impurities in the water are exchanged with the hydrogen and/or hydrogen-oxygen root ions on the resin, it must be "regenerated" The regeneration procedure is the opposite of the purification procedure, which uses hydrogen ions and hydrogen oxygen root ions for regeneration and exchanges impurities attached to the ion exchange resin
When ion exchange is combined with other purified water quality methods (e.g reverse osmosis, filtration, and active carbon adsorption), ion exchange will play a very important role in the entire purification system Ion exchange can effectively remove ions, but it can not effectively remove most of the organic matter or microorganisms Microbes can be attached to the resin and used as a medium for resin, allowing the microorganism to grow quickly and produce a heat source Therefore, it needs to be designed to work with other purification methods
Biochemical instrument with pure water machine introduction and selection biochemical instrument in the analysis of chemical element content can measure the less non-disturbing elements the better, the need to wash the test products with ultra-pure water to more effective calibration Pure water machine for biochemical analysis is an ultra-pure water preparation instrument designed for fully automatic biochemical analyzers Biochemical analysis of pure water machine according to the biochemical instrument needs ultra-pure water consumption characteristics, the general design of 10L/h to 60 liters per hour
The requirements of ultra-pure water for ultra-pure water with pure water machine stoic s/he is generally required for ultra-pure water resistance
Biochemical analysis ultra-pure water machine design has certain characteristics:
Equipped with reverse osmosis membrane, purification package is larger than ordinary ultrapure water specifications , because the water production brought about by the rapid replacement of supplies, biochemical analysis of ultra-pure water machine usually consider the design of saving supplies
Biochemical analyzer in the hospital inspection department more applications, medical department spending time has a certain particularity, requires the chemical and biological instrument supplies replacement is convenient and fast, after-sales service in place in a timely manner These requirements make biochemical lyse ultrapure water machines easier to replace user maintenance and consumables
Biochemical analysis type ultra-pure water machine is usually floor-to-ceiling, increase the space in the machine to fill more supplies, reduce the frequency of supplies replacement.
