摘要
本文采用顶空气相色谱法测定化妆品中甲醇的含量。用氢火焰离子化检测器检测 ,化妆品中甲醇的最低检测浓度为 1 .5mg/kg,在样品中加标量分别为 2 0 mg和 4 0 mg时 ,回收率为 91 .9% -95.2 % ,依本法取两份样品分别测 6次 ,变异系数为 1 .6% -2 .8%。
The method of this paper ueses the HSC to determine methanol in cosmetics.The sample is determined with hydrogen flame ionization detector.The minimum detective limit is 1.5mg/kg. Add the standards 20mg and 40mg to the sample,and the recovery is 91.9%-95.2%.Determining two samples six times,then the variable coefficients is 1.6%-2.8%.
