What can the structure of gas chromatograph be divided into?

The gas chromatograph is mainly composed of gas path system, sampling system, separation system, temperature control system and detection and recording system.

A, gas system:

Include gas source, gas purification, gas flow rate control and measurement. So as to obtain pure carrier gas with stable flow rate.

Second, the sampling system:

Comprises a sampler and a gasification chamber. Samplers are divided into gas samplers and liquid samplers, and the gasification chamber is a device for instantly gasifying liquid samples.

Third, the separation system:

According to the different distribution coefficients or adsorption coefficients of each component in mobile phase and stationary phase, the separation of each component can be realized in chromatographic column.

Fourth, the temperature control system:

Control the temperature of gasification chamber, column box and detector.

Verb testing and recording system;

Convert the concentration or mass of each component into an electrical signal and record it.
