A biochemical analyzer is an instrument that measures a specific chemical composition in body fluids based on the photoelectric colorimetric principle. Biochemical analyzer is a testing equipment that part or all of the steps in biochemical analysis such as sampling, adding reagents, removing interferents, mixing, holding, colorimetric, result calculation and cleaning are done by instruments that imitate manual operation.
The biochemistry machine is mainly used to provide clinical biochemistry, clinical hematology, clinical immunology and other aspects of testing programs for hospitals at all levels of laboratory medicine. The biochemistry analyzer can be used to test clinical biochemical indicators such as liver function, kidney function, blood lipids, diabetes, infection, rheumatology and immunity. It can provide an important scientific basis for the diagnosis, treatment and prevention of diseases, and is a necessary testing equipment for hospitals.
1. Classification of biochemical instrument
According to the degree of automation is divided into semi-automatic and fully automatic biochemical analyzer. Compared with semi-automatic biochemical analyzer, fully automatic biochemical analyzer is an optical-electro-mechanical integrated clinical biochemical and pathological testing equipment, which has the characteristics of fast, simple, sensitive, accurate, standardized and microscopic.
-
1)According to the structure of reaction device, it is divided into pipeline continuous flow type, discrete type and centrifugal type biochemical automatic analyzer.
-
2)According to the reaction mode, it is divided into liquid and dry biochemical auto-analyzer. Dry chemistry analyzers are currently mostly used in emergency and on-site laboratory tests.
-
3)According to the complexity of the instrument and functional classification is divided into small, medium and large automatic analyzers.
-
4)According to the reaction speed is divided into low speed, medium and high speed, and high speed. Low speed: 800 speed or less, including 200 speed, 300 speed, 400 speed, 600 speed; medium and high speed: 800 speed, 1000 speed, 1200 speed; high speed: 1600 speed, 1800 speed, 2000 speed.
2. High-speed biochemical instrument classification
For high-speed biochemical analyzer, it can be divided into modular machine and single machine.
The advantage of the module machine is that it can add modules as the hospital test volume increases. The disadvantage of the modular machine is that multiple analysis modules, sharing a sample bin. When there are multiple modules, there will be a relative shortage of sample bins. In addition to that, most of them need fixed connection devices when connecting to the pipeline.
The advantage of the single machine is that the single machine occupies a small area and can be directly connected to the pipeline.
