Introduction and classification of liquid chromatography analyzers

Liquid chromatography analyzers are widely used as analytical instruments in the fields of chemistry, biology, medicine, pharmaceuticals and other fields. It is an analytical instrument that separates and detects sample solutions through a column device. According to the properties of the sample molecules, they interact with the stationary phase in the column and are continuously separated and purified under a certain mechanism.
    Liquid chromatography analyzers work by separating sample molecules based on their chemical nature, molecular size, and other properties. The sample is separated by the stationary phase in the column, and the type and content of the sample molecules are determined based on the signals generated during the separation and detection process.
    There are many types of liquid chromatography analyzers, including normal phase, reversed phase, ion exchange, gel permeation, etc. They are suitable for different sample types and purposes and can analyze molecules such as proteins, nucleic acids, organic matter, pharmaceuticals, etc.
    Liquid chromatography analyzers have the advantages of high sensitivity, high resolution, and high sample throughput. They can quickly and accurately obtain information about sample molecules, which is of great significance for research and applications in chemistry, biology, and medicine.
