Multi-channel automatic liquid samplers are used to automatically inject pressurized liquid sample (LPG) into the analyzer in batches. It is mainly used for the analysis of petrochemical liquids. The research shows that the automatic sampler has a high degree of automation and good continuity, and the correlation coefficient of the standard curve is more ideal than that of the manual sampling analysis. In order to reduce the error of the operator in sampling, the automatic sampler has been widely used in gas chromatography analysis.
