液相色谱-毛细管气相色谱/质谱离线联用分析烟草中的挥发性及半挥发性成分 - Analysis of volatile and semi-volatile compounds in tobacco using off-line combination of liquid chromatography and capillary gas chromatography-mass spectrometry

建立了一种用于烟草样品中挥发性、半挥发性成分分析的液相色谱-毛细管气相色谱/质谱(LC-CGC/MS)离线联用方法。研究了LC-CGC/MS的分离机理。LC分析选用氨基分析柱(250mm×2.0mm,5μm)作为分析柱,正己烷-二氯甲烷-乙腈(90∶6.6∶3.4,v/v/v)作为流动相,对挥发性、半挥发性成分进行分离,收集得到5个馏分,并存放在5个氮吹瓶中。多次进样并收集相同时间段的馏分,氮吹浓缩至1mL,然后分别进行CGC/MS分析,所用的CGC柱为DB-5MS(60m×0.25mm×0.25μm)。结果显示,与直接采用CGC/MS分析相比,采用LC-CGC/MS分析复杂样本的效果更好,定...

1A method of off-line combination of liquid chromatography and capillary gas chromatography-mass spectrometry(LC-CGC/MS) was established for the analysis of volatile and semi-volatile compounds in tobacco.The separation mechanism of volatile and semi-volatile compounds was studied.An LC column of 250 mm×2.0 mm packed with 5 μm amino-bonded silica was used as stationary phase for the separation.n-Hexane/dichloromethane/acetonitrile(90∶6.6∶3.4,v/v/v) was used as mobile phase.Five fractions from one LC run were collected in five nitrogen-blowing flasks,separately.The same fractions from 10 LC runs were combined together and concentrated to 1 mL by nitrogen blowing,and then were analyzed by CGC/MS.The column of DB-5MS(60 m×0.25 mm×0.25 μm) was used for CGC/MS analysis.Comparing with direct CGC/MS analysis of the same sample,the LC-CGC/MS system is suitable for a complex sample,and has a higher reliability of qualitative analysis.
