PTV-GC/MS-SIM法检测卷烟烟气中的BaP

Analysis of Benzoapyrene in Cigarette Smoke Using PTV-GC/MS-SIM

摘要: 采用程序升温汽化(programmed temperature vaporization, PTV)大体积进样与气相色谱-质谱选择离子扫描模式（GC/MS-SIM）联用，检测了卷烟主流烟气中苯并a芘（benzoapyrene BaP），优化了PTV-GC/MS-SIM检测卷烟烟气BaP的参数。样品经反相C18固相萃取柱（solid-phase extraction, SPE）纯化后的洗脱液不再需要浓缩，直接应用PTV技术进样，提高了洗脱液的利用率，缩短了分析时间，提高了GC/MS-SIM检测卷烟烟气BaP的灵敏度。

Abstract: Benzoapyrene (BaP) in the main stream cigarette smoke was determined by programmed temperature vaporization gas chromatography-mass spectrometry with selective-ion monitoring(PTV-GC/MS-SIM) and large volume injection. The parameters in the determination of BaP in cigarette smoke by PTV-GC/MS-SIM were optimized. Effluents of samples did not required to be concentrated any more after being purified by reverse-phase C18 solid-phase extraction (SPE). Sampling using PTV technology directly increased the utilization ratio of effluents, saved analysis time, and enhanced determination sensitivity of BaP in cigarette smoke by GC/MS-SIM.
