气相色谱法测定烟道气组成

Determination the Composition of Flue Gas by Chromatograph

研究了用HP6890N型气相色谱仪分析烟道气的方法 通过阀的切换使样品流过不同的色谱柱,从而达到一次进样就能对烟道气中各组分进行自动分析的目的 利用标准样品获得各组分相对校正因子,采用外标法定量 一氧化碳的检测下限为0.05%,氧气的检测下限为0.1%,二氧化碳的检测下限为0.1%

The composition of flue gas is analyzed with a HP6890N gas chromatograph in which the samples go through different columns by switching the valves, and hence all components are determined by one injection. The quantification is applied by external standard method, while the individual relative correction factor is acquired at the mean value. The lowest detectable content for carbon monoxide 0.05%,oxygen and 0.1%,carbon dioxide is 0.05%,0.1% and 0.1% respectively.
