Function and Use

Headspace injector is a sample pretreatment device for gas chromatography analysis. Compared with other sample pretreatment methods, such as solvent extraction and thermal analysis, it is simpler and more practical, has higher working efficiency, and has good reproducibility of chromatographic analysis results. It is one of the preferred methods for gas chromatography measurement analysis.
