【摘要】：建立了氣相色譜-三重四極桿質(zhì)譜(GC-MS/MS)同時(shí)測(cè)定煙絲中73種香氣物質(zhì)的分析方法。樣品用無(wú)水乙醚振蕩提取,提取液經(jīng)過(guò)濾后直接進(jìn)入DB-5MS色譜柱(30 m×0.25 mm,0.25μm)分離,通過(guò)優(yōu)化質(zhì)譜參數(shù),可有效降低復(fù)雜基質(zhì)和重疊峰的干擾,同時(shí)采用多反應(yīng)監(jiān)測(cè)(MRM)模式測(cè)定,內(nèi)標(biāo)法定量。結(jié)果表明,目標(biāo)物在各自的線性范圍內(nèi)線性關(guān)系良好(r~20.99),低、中、高3個(gè)水平的加標(biāo)回收率為70.0%~122.3%,相對(duì)標(biāo)準(zhǔn)偏差(RSD)為1.6%~20.4%。該方法具有前處理簡(jiǎn)單、準(zhǔn)確靈敏的特點(diǎn),適用于煙絲樣品中73種香氣物質(zhì)的檢測(cè)。
[Abstract]:A gas chromatography-quadrupole mass spectrometry (GC-MS / MS) method was established for the simultaneous determination of 73 aroma substances in tobacco. The samples were extracted by anhydrous ether oscillating, and the extract was filtered directly into the DB-5MS chromatographic column (30m 脳 0.25mm-1. 25 渭 m). The mass spectrometry parameters were optimized. It can effectively reduce the interference of complex matrix and overlapping peaks, at the same time, the method of multi-reaction monitoring MRM is used, and the quantity of internal standard is determined. The results show that the linear relationship of the target material in their respective linear range is good, low, middle, low, low, low, low, low, low, low, low, low, low, low, low, low and low. The recoveries of the three levels were 70.0 and 122.3, and the relative standard deviation (RSD) was 1.60.The method was simple, accurate and sensitive, and could be used for the determination of 73 aroma substances in tobacco samples.
