气相色谱法用于煤气的成分分析,可以发挥它的快速、精确的特点,从现行操作方法来看,对各组分的分离、标准气体(下称标气)的制备和测定,尚有一些问题需要解决,以求得进一步发挥它的优势。我们斜对这些问题,采用多组分混合标准气体和相对校正因子计算等方法,取得较好的效果。1.仪器和分析条件使用南京分析仪器厂的CX-105型气相色谱仪来分析发生炉煤气的成分。该仪器是以热导池为检测器的简型装置,具有并联补偿双柱双气路。色谱分离柱为
Gas chromatography for gas composition analysis, can play its fast and accurate features, from the current operating point of view, the separation of components, the standard gas (hereinafter referred to as the standard gas) preparation and determination, there are still some The problem needs to be solved in order to further its advantages. We obliquely to these issues, the use of mixed multi-component standard gas and relative correction factor calculation methods, and achieved good results. 1. Instruments and Analytical Conditions The composition of the producer gas was analyzed using a CX-105 GC at Nanjing Analytical Instrument Factory. The instrument is based on the thermal conductivity of the detector as a simple device with parallel compensation double-column double gas. Chromatography column
