摘　　要：采用直接顶空进样气相色谱-质谱法测定纺织品中二甲萘烷醇(GSM)、2-异丁基-3-甲氧基吡嗪(IBMP)和2-甲基异茨醇(M IB)异味物质,考察了顶空加热时间、温度等因素对异味化合物回收率的影响,结果表明:2-异丁基-3-甲氧基吡嗪、2-甲基异茨醇和二甲萘烷醇检出限分别为0.01 mg/kg、0.005 mg/kg、0.003 mg/kg。加标回收率依次为在81%、95%、84%,相对标准偏差均小于7%,该测试方法简单、快捷、可靠,结果令人满意。Analysis of 2-isopropyl-3-methoxypyrazine,2-methylisoborneol and geosmin in textile by HS/GC/MS,and the effect of heat time and temperature on the recovery were investigated.The result showed that the limit of detection for 2-isopropyl-3-methoxypyrazine,2-methylisoborneol and geosmin were 0.01 mg/kg,0.005 mg/kg and 0.003 mg/kg,respectively,the recoveries were 81%,95% and 84%,respectively and relative deviation was less than 7%.This method for determination of odorous substances in textile was simple,quickly and reliable,with satisfactory result.
