摘    要:本文提出一种添量加减的气相色谱法(即在内标法的基础上在试样中添加甲醇标样进行色谱分析,将检出的甲醇量减去添加的甲醇量,即为样品中的甲醇含量),解决了白酒甲醇含量在0.2g/L以下用20%DNP 7%吐温80色谱柱检不出的问题.

关 键 词:气相色谱  添量加减法  甲醇测定  探讨

Abstract:This text puts forward an analysis of gas chromatograms through the adding and subtracting methanol (namely adds methanol in the sample and carries on the analysis of chromatograms on the basis of standard inside, the quantity of methanol determined deducts which of the added is the quantity of methanol the sample contained ), solves the problem of the contents of methanol in white spirit under 0.2g/L is not determined by 20% DNP+7% TWEEN 80 column.
Keywords:gas chromatogram  the adding and subtracting methanol  determining methanol  discussing
