本文采用大孔径交联PEG-20m毛细管柱气相色谱法分析酒中杂醇及车间空气中苯、甲苯、二甲苯。色谱效果好,分析速度快,定量准确。现将实验方法和结果介绍如下。实验使用上海分析仪器厂103型气相色谱仪,FID检测器,色谱柱为交联PEG-20m柱,内径0.5mm,柱长15m。色谱条件为:载气(高纯氮):30ml/min;分流比:50:1;
In this paper, macroporous cross-linked PEG-20m capillary column gas chromatography analysis fusel alcohol and workshop air benzene, toluene, xylene. Chromatography, analysis speed, quantitative accuracy. The experimental methods and results are described below. Experiments using Shanghai Analytical Instrument Factory 103 gas chromatograph, FID detector, the column was cross-linked PEG-20m column, an inner diameter of 0.5mm, column length 15m. Chromatographic conditions: carrier gas (high purity nitrogen): 30ml / min; split ratio: 50: 1;
