摘  要：
为选择性测定烟用白乳胶中7种苯系物,建立了静态顶空-气相色谱质谱选择离子定量的测定方法。样品经140℃、30 min静态顶空后,以2-己酮为内标,采用HP-INNOWAX柱,气相色谱-质谱选择离子模式检测,内标法定量。该方法对7种苯系物的定量检测限为0.008～0.01 mg/kg,加标回收率为88.9%-104.5%,RSD<5%,效果良好。

摘  要：
A method based on static headspace gas chromatography-mass spectrometry(SHS-GC/MS) and internal standard was developed to selectively determine seven benzene series components contents in cigarette adhesive.Experimental conditions such as headspace temperature,headspace time and analytical conditions of GC-MS were optimized.Cigarette adhesive samples were treated at 140℃ for 30 min.Head-space vapor of final extraction was injected into a HP-INNOWAX column and detected by MS.The target compounds were quantified by internal standard method under selected ion monitoring mode.Results showed that: the recoveries ranged from 88.9% to 104.5%,with relative standard deviations(RSDs) e less than 5%.The linear range was from 0.01 to 0.5 μg/mL with a good linear determination coefficient(R2>0.999) and limits of quantification were 0.008~0.01mg/kg.The method is accurate,simple and rapid.
