摘要
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 ,相对标准差小于 3% 。
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.
