Application Publication Number: CN106198796A Published Application Date: 2016.12.07 Applicant: 中华 中 烟 工业 有限 责任 公司 Abstract The present invention discloses a method for the determination of cigarette mainstream smoke by supercritical fluid chromatography (SFC) -chromatographic-mass spectrometry (GC-MS) The method of benzo [a] pyrene in air. In the method, internal standard substance and cyclohexane solution are added to the filter plate for capturing the total particulate matter of the mainstream cigarette smoke after the cigarette is smoked, and the solution is subjected to ultrasonic extraction, and the extract is separated and purified by supercritical fluid chromatography to cut The fractions containing benzo [a] pyrene were analyzed by GC-MS. Based on the area ratio of the target peak and the internal standard peak of the isotope
