汽车发动机排气中总烃的气相色谱分析

The Total Hydrocarbons are Analysed by Gas Chromatography in an Auto Engine Exhaust

本文采用气相色谱法定性，氢火焰离子化定量分析汽车发动机尾气中总烃含量。以此测定催化剂的净化效果。介绍了分析原理和方法。文中阐述了色谱条件的形成、标准气的配制、燃料及工作条件的选择。最后通过实验数据的比较，找出最佳催化剂。

In this paper,we analysed the total hydrocarbons volume in an auto engine exhaust;both qualitative by the gas chromatography and quantitative by the hydrogen flame and ionized.Using one ,the purge efficacy of the catalysts is measured.The paper introduced the analysis principle and method to form of the chromatography condition,to make up of the standard gas,to choose of the fuel and work condition.Last,we find the best catalyst by means of comparing of the test date.
