气相色谱法测定苯系物标准样品

提出了以二硫化碳为稀释剂，用氯苯作内标物，采用程序升温，调节载气流量，在一根色谱柱上使苯系物标准样品中的7个组分得到完全分离。对苯系物标准样品进行多次测定，各组分的测定结果均在标准样品的保证值范围内，相关标准差小于3％，方法的准确度和精密度均较好。

To Determine Benzene Standard Samples Using Gas Chromatography

Taking CS 2 as diluent, chlorobenzene as internal standard, programmed increasing temperature, seven components were separated from benzene standard samples in a chromatographic column. Many times experiments were undertaken, and the detection results were all limited among the assurance scope. The relative standard deviation was less 3%. There had a good accuracy.
