白酒特征成分气相色谱分析误差的探讨
Discussion on errors in liquor characteristic components analysis by gas chromatograph
摘要
Abstract
The influence of the determination of the composition of liquor characteristic components by gas chromatography, such as the gas chromatography column, solvent, sampling methods, quantitative methods and other aspects, was analyzed and discussed. The results showed that the stationary phase of the gas chromatography column Significantly influenced the sequence of the characteristic components at the chromatogram, and improper selection of the gas chromatography column would cause the errors of the quantitative a-nalysis results. The solvent would make peak order change, and then lead to qualitatively incorrect, or maybe introduce some interference component. Sample volume and the split ratio mainly affecting the chromatographic separation. Different quantitative methods may have great influence on the quantitative results. In the process of a-nalysis, according to the liquor testing project and objective, 60% ethanol ( HPLC pure ) aqueous as solvent, suitable chromatography column, optimized chromatographic conditions and quantitative method should be adopted to reduce errors and provide more accurate data.关键词
