PTV-GC/MS-SIM法檢測卷煙煙氣中的BaP

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

摘要: 采用程序升溫汽化(programmed temperature vaporization, PTV)大體積進(jìn)樣與氣相色譜-質(zhì)譜選擇離子掃描模式（GC/MS-SIM）聯(lián)用,，檢測了卷煙主流煙氣中苯并a芘（benzoapyrene BaP）,，優(yōu)化了PTV-GC/MS-SIM檢測卷煙煙氣BaP的參數(shù)。樣品經(jīng)反相C18固相萃取柱（solid-phase extraction, SPE）純化后的洗脫液不再需要濃縮,，直接應(yīng)用PTV技術(shù)進(jìn)樣,，提高了洗脫液的利用率,，縮短了分析時間，提高了GC/MS-SIM檢測卷煙煙氣BaP的靈敏度,。

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.
