用毛细管气相色谱法研究分离和测定二硝基甲苯异构体的方法,在填充柱上涂以典型的固定液,测定二硝基甲苯异构体的相对保留值,发现OV-225和XE-60两种固定液是分离二硝基甲苯六种异构体较好的固定液,因此用OV-225涂于玻璃毛细管柱上进行二硝基甲苯异构体的定量分析。
The method of separation and determination of dinitrotoluene isomers was studied by capillary gas chromatography. The relative retention of dinitrotoluene isomers was determined by coating the packed column with a typical fixative. It was found that OV-225 and XE- 60 The two fixatives are a good fixative for the separation of six isomers of dinitrotoluene. Therefore, a quantitative analysis of the dinitrotoluyl isomer was performed on a glass capillary column using OV-225.
