Chromatography

A chromatograph is an instrument that is used to analyze chemical compounds in various media, such as air, water, soil and other objects. It is based on the principle of separating substances based on their physical and chemical properties, such as density, boiling point, etc.

A chromatograph consists of several components, including a column, which is the main element of the instrument. A column is a tube filled with a special sorbent that retains the molecules of the analyte. The column is then connected to a detector, which determines the concentration of the substance in the gas or liquid stream passing through the column.

There are several types of chromatographs, which differ in operating principle and detector type. For example, gas-liquid chromatographs are used to analyze gas mixtures, and liquid chromatographs are used to analyze liquid solutions.

The use of chromatography is widespread in scientific research, medicine, industry and other fields. For example, chromatography is used to determine the composition of air, water and soil, as well as to control the quality of food and medicine.

In general, a chromatograph is an important tool for the analysis and quality control of various media, as well as for scientific research in various fields.

Chromatograph is a class of instruments for separation (purification, concentration) and analysis of mixtures of gases and vapors of various natures (including complex ones) using adsorption or physical chromatography; Partition and gas chromatography methods are also used.
