I. Introduction
Autoanalyser is a kind of instrument that can automatically complete chemical and biological experimental analysis, which is widely used in the fields of medicine, environmental monitoring, pharmaceuticals and so on. It can quickly and accurately detect various substances and provide important data support for scientific research, production and medical treatment.
II. the working principle of automatic analyser
Automatic analyser is usually composed of sampler, feeder, reaction system, detection system and control system. Its working principle is roughly as follows: first, the sampler from the sample to be tested to take out a certain amount of liquid or solid, and will be sent to the sampler. The function of the feeder is to dilute, mix or separate the sample for subsequent reaction. Next, the reaction system reacts the sample with reagents to produce the appropriate chemical or physical changes. The detection system, on the other hand, detects the signals generated during the reaction process by means of light, electricity and heat, and converts the signals into measurable electrical signals. Finally, the control system coordinates the work of each part to ensure the automation and accuracy of the whole analysis process.
III. the classification of automatic analyser
According to the type of detected substances: automatic analyser can be classified according to the different types of detected substances. For example, the water quality automatic analyser is used to detect various ions and organic matter in the water; soil heavy metal automatic analyser is used to detect heavy metal elements in the soil; food heavy metal automatic analyser is used to detect heavy metal elements in the food and so on.
According to the detection principle: automatic analyser can also be classified according to the different detection principles. For example, spectrophotometric autoanalyser uses the principle of spectrophotometer for detection; electrochemical autoanalyser uses electrochemical method for detection; chromatographic autoanalyser uses the principle of chromatography for detection and so on.
According to the application field: automatic analyser can also be classified according to its application field. For example, the medical automatic analyser is mainly used for medical laboratory biochemical analysis and immunoassay analysis; environmental protection automatic analyser is mainly used for environmental monitoring stations of water quality and atmospheric pollutants monitoring; agricultural automatic analyser is mainly used for soil and crop nutrient determination and so on.
IV. the application of automatic analyser
Medical diagnosis: in the medical field, automatic analyser is widely used in clinical chemistry, immunology and haematology and other laboratory tests. By analysing the components of blood, urine and other body fluids, doctors are able to quickly and accurately diagnose diseases, formulate treatment plans and monitor treatment effects. For example, fully automatic biochemical analysers can test liver function, kidney function, blood sugar, blood lipids and other indicators, providing a basis for the diagnosis of liver disease, kidney disease, diabetes and other diseases.
Environmental monitoring: In the field of environmental monitoring, automatic analysers are mainly used for monitoring pollutants such as water quality, air and soil. By analysing the heavy metals, organic matter and nutrients in the water, as well as the PM2.5, NOx and SO2 in the atmosphere, the automatic analyser can help the environmental monitoring agency to discover the source of pollution in a timely manner, and provide a scientific basis for environmental protection.
Pharmaceutical industry: In the pharmaceutical industry, automatic analysers are mainly used in drug research and development, production and quality control. By analysing and testing the components of drugs to ensure the effectiveness and safety of drugs. In addition, automatic analysers can also be used for quality control and production process monitoring of biological products and vaccines.
Agricultural field: In the agricultural field, automatic analysers are mainly used in the determination of nutrients in soil and crops, and the quality testing of agricultural products. By analysing nutrients such as nitrogen, phosphorus and potassium in the soil, as well as detecting pesticide residues and nutrients in agricultural products, autoanalysers can help farmers apply fertilizers and medicines reasonably, and improve the quality and yield of agricultural products.
Scientific research: In the field of scientific research, automatic analysers are mainly used for research in the fields of chemistry, biology and earth science. Through qualitative and quantitative analysis of various substances, as well as simulation and experimental research, autoanalysers provide important data support and experimental means for researchers.
As an important chemical and biological experimental instrument, autoanalyser has been widely used in medical diagnosis, environmental monitoring, pharmaceutical industry, agricultural field and scientific research. It can quickly and accurately detect the composition and content of various substances, providing important data support and practical means for the research and development of related fields. With the continuous development of science and technology, it is believed that the performance and application scope of auto analyser will be further expanded and improved, making greater contribution to the progress and development of human society.
