Gas chromatograph and control method thereof

Abstract

The invention relates to the technical field of detection equipment, in particular to a gas chromatograph and a control method thereof.The gas chromatograph comprises a chromatograph body and further comprises a sample injection system, a gas chromatograph control system and a gas chromatograph control system, the separation system is used for physically separating different components in a sample according to the difference of distribution coefficients of the different components between a mobile phase and a stationary phase, the correction assembly is arranged, so that the correction assembly is firstly focused on the upper area of the sampling needle in the correction process, it is ensured that the firm part is properly adjusted, and the correction accuracy is improved; once the upper part reaches an ideal straight line state, the correction component gradually extends downwards along the whole sampling needle body to generate the acting force, so that the previous correction effect is favorably verified and consolidated, the needle tip area of the sampling needle is ensured not to be missed, and the situation of omission that only the needle tip is kept originally bent is favorably prevented.
