Research on Multifunctional Gas Chromatography Sample Pretreatment Apparatus

Abstract:

Multifunctional gas chromatography sample pretreatment apparatus (hereinafter referred to as pretreatment apparatus), which is developed on the basis of gas purge micro-syringe extraction (GP-MSE) technique, is a gas chromatography (GC) sample pretreatment apparatus that integrates extraction, purification, concentration and predissociation. The quantitative and qualitative analysis results analyzed by GC-MS for volatile oil that extracted from the plant samples by steam distillation method and pretreatment apparatus, show that the volatile components extracted by the apparatus outnumber the ones extracted by steam distillation method clearly, and the content of major constituents extracted by the apparatus is higher. The apparatus have advantages of low consumption of agentia, short extraction time, high enrichment efficiency, simple structure, convenience in usage and low operating costs. The apparatus can be widely used in the areas of medicine, agriculture, food, quality control to the sample pretreatment of solid or liquid sample.
