气相色谱-质谱联用法测定染料中苯胺类化合物
|
摘要
本文采用气相色谱-质谱联用仪测定染料中的19种苯胺类化合物。用二氯甲烷作为溶剂,提取出染料中的苯胺类化合物,在气相色谱上进行分离,使用质谱检测器检测,用特征离子峰面积外标法进行定量。19种苯胺类化合物的测定结果相对标准偏差小于2%,检测回收率为65%～120%,定量限为0. 02～0. 5 mg/kg。
A gas chromatography-mass spectrometry( GC-MS) was used to determine 19 aniline in dyestuff. Aniline compounds in dyes were extracted with dichloromethane as solvent,separated by gas chromatography,detected by mass spectrometry and quantified by characteristic ion peak area external standard method. The relative standard deviation of the determination results of 19 aniline substances is less than 2%,the detection recovery is 65% ～ 120%,and the quantitative limit is 0. 02 ～ 0. 5 mg/kg.
