摘要
采用毛细管气相色谱法,对室内装饰装修材料中的苯、甲苯、二甲苯的测定进行了改进。称取样品后,用N,N-二甲基甲酰胺稀释定容,CBP20毛细管柱分离,可同时测定苯、甲苯、二甲苯的含量,数据准确,操作简单。
A modified method for determination of benzene, toluene and xylene in decorative material by gas chromatography with capillary column is described. The sample was solvated with N,N-dimethylformamide, and detected with FID. The variable coefficient was between 0.72% to 3.73% . This method is simple and rapid.
