采用综合二维气相色谱（GC×GC） -快速获取飞行时间（TOF）质谱（MS）分析烟草提取物中农药成分。重点是样品的定性表征，使用自动峰查找和光谱反褶积软件识别提取物中的14种农药。根据对数据的人工审查确定了另外两种农药。使用基质匹配标准的烟草提取物加标2.5至50ng/mL浓度的多种有机氯和有机磷农药，以证明线性和GC×GC消除可能导致定量偏差的干扰的好处。
Comprehensive two-dimensional gas chromatography (GC×GC) with fast acquisition time-of-flight (TOF) mass spectrometry (MS) was used to analyze a tobacco extract for pesticides. The emphasis was on qualitative characterization of the sample, using automated peak find and spectral deconvolution software to identify 14 pesticides in the extract. Two additional pesticides were located based on manual review of the data. Matrix-matched standards of tobacco extract spiked with 2.5 to 50ng/mL concentrations of numerous organochlorine and organophosphorus pesticides were used to demonstrate linearity and the GC×GC benefit of eliminating interferences that might contribute to quantification bias.
