摘    要:采用单一进样口六通阀进样、毛细管柱二维气相色谱仪三通路分离塔柱分离系统、采用氢离子化检测器分别产生信号,测定环境空气中的非甲烷总烃。通过柱分离系统将样品平均分配到不同类型的两个毛细管色谱柱,分别测定总烃及甲烷。方法简单、快速,最大程度地保证了进样的一致性,从而保证了分析结果的准确性。

关 键 词:二维气相色谱法  总烃  非甲烷总烃

Abstract:Non-methane hydrocarbons in air are determined by using a single injector six-way valve for sample injection,capillary column gas chromatograph three-way-splitter column separation system,and adopting hydrogen ionization detector.Total hydrocarbons and methane are determined,respectively,by average assigning the samples to two capillary columns through the column sample separation system.The method is simple,fast and insures the precision and accuracy of the results.
Keywords:two-dimensional gas chromatography  total Hydrocarbons  non-methane hydrocarbons
