建立一种液质联用法快速测定纺织品中2-(4-叔丁基苄基)丙醛化合物的方法,将样品经过振荡提取过滤后,直接上机测试,以乙腈/水(80/20)为流动相、用ZORBAX Eclipse Plus C18色谱柱分离,MRM模式下外标法定量.在优化的试验条件下,检出限为1.0 mg/kg,定量限为2.0mg/kg,加标回收率为80.8％～103.8％,相对标准偏差为1.5％～8.1％,该测试方法操作简单、灵敏度好,可快速测试纺织中的2-(4-叔丁基苄基)丙醛.
Research on the detection method of 2-(4-tert butylbenzyl)propanal in textiles
A liquid chromatography-mass spectrometry(LC-MS)method was established for the rapid determination of 2-(4-tert butylbenzyl)acetaldehyde compounds in textiles.After shaking extraction and filtration,the samples were directly tested on the machine.Acetonitrile/water(80/20)was used as the mobile phase and separated using ZORBAX Eclipse Plus C18 chromatography column.The external standard method was used for quantification in MRM mode.Under optimized experimental conditions,the de-tection limit is 1.0 mg/kg,the quantification limit is 2.0 mg/kg,the spiked recovery rate is 80.8％～103.8％,and the relative standard deviation is 1.5％～8.1％.This testing method is simple to operate and has good sensitivity,and can quickly test 2-(4-tert butylben-zyl)propanal in textiles.
