High performance Liquid chromatography (HPLC): This is an important branch of chromatography, also known as "high pressure liquid chromatography", "high speed liquid chromatography" and so on. HPLC is widely used for its high separation efficiency, rapid analysis and wide range of applications.
Gas chromatography (GC): It is mainly used for the analysis of volatile and semi-volatile organic compounds, especially in environmental monitoring, drug detection, and petrochemical product analysis.
Thin Layer chromatography (TLC) : This is a relatively simple and economical chromatography technique that is often used for rapid analysis and purity detection.
Ion exchange chromatography: It is mainly used for the separation of ionic compounds, such as proteins, nucleic acids and other biological macromolecules.
Affinity chromatography: The use of specific interactions between biomolecules to separate, often used for the purification of enzymes, antibodies and other bioactive substances.
Gel permeation chromatography (GPC): mainly used for the determination of molecular weight distribution of polymer compounds and polymer characterization.
Ultra-high performance liquid chromatography (UHPLC): UHPLC has higher resolution, speed and sensitivity than HPLC.
Capillary electrophoresis (CE): Although not chromatography in the traditional sense, it is also an analytical technique that uses electric field forces to separate, and is sometimes classified as one of the chromatographic techniques.
