Abstract

The invention relates to a method for selectively determining benzene series in smoke intercepted by a cigarette filter through adopting static headspace-gas chromatography / mass spectrometry. In order to selectively determine seven kinds of benzene series in smoke intercepted by the cigarette filter, a determining method of using static headspace-gas chromatograph and mass spectrometry to select ion quantification is adopted. According to the detecting method, the quantitative detection limit to the seven kinds of benzene series is 0.003-0.005 mug / cig, the standard recovery rate is 86.2-102.8, and the relative standard deviation is smaller than 5 percent. The detecting method has the advantages of simplicity in operation, quickness in determination and high accuracy and sensitivity, and provides a technical support for selecting filter materials and selectively reducing the release amount of the benzene series in cigarette smoke.

Description

technical field [0001] The invention relates to a method for measuring benzene series in cigarette filter-tipped smoke, in particular to a method for selectively measuring benzene series in cigarette filter-trap smoke by using static headspace-gas chromatography mass spectrometry. Background technique [0002] Cigarette mainstream smoke is a complex mixture system, in which benzene series belong to a class of volatile aromatic compounds, mainly including: benzene, toluene, ethylbenzene, p-xylene, o-xylene, m-xylene and Styrene, etc., if the substance is inhaled into the human body, it will directly or indirectly endanger the health of the human body. Cigarette filters can effectively filter out some harmful components in cigarette smoke. At present, there have been reports on specific harmful components in tobacco, such as nitrosamines, carbonyl compounds, phenolic compounds, pesticide residues, and acrylamide. There are few reports on the determination and analysis methods...
