Automatic Detection and Application of GC-1690 Gas Chromatograph

This paper takes the GC-1690 gas chromatograph as an example to describe the working principle and the host structure of the GC-1690 gas chromatograph in detail. Through the experiment, the method of using the instrument was described. The analysis of the experiment using the N2000 chromatography workstation has certain significance for the detection and research of pesticide residues, food, petroleum and petrochemicals, medicine and health.
