Embodiment 1

[0031] The method for simultaneously measuring 16 kinds of polycyclic aromatic hydrocarbons in cigarette mainstream smoke of the present embodiment comprises the following steps:

[0032] 1) Suck the balanced and screened brand 1 cigarettes according to the standard smoking conditions stipulated in YC / T29-1996, use a Cambridge filter to capture the particulate matter in the mainstream smoke of 5 cigarettes, and then use the Cambridge filter Transfer the slices into a 100ml ground-mouth Erlenmeyer flask and lay it flat on the bottom of the bottle, add 50μL of internal standard solution, and then add 30ml of methanol to shake and extract for 40min to obtain methanol extract;

[0033] The internal standard solution is a mixed solution of 5 deuterated internal standards, and the 5 deuterated internal standards are naphthalene-d8, acenaphthylene-d10, anthracene-d10, benzo[a]anthracene-d12, benzo [a] pyrene-d12, the solvent is methanol; in the internal standard solution, the content...

Abstract

The invention discloses a method for simultaneously measuring 16 polyaromatic hydrocarbons in mainstream smoke of cigarettes. The method comprises the following steps of (1) trapping dry particulate matters in the mainstream smoke of the cigarettes through a Cambridge filter, then transferring the Cambridge filter into an extraction container, adding an internal standard mixed solution, and then adding methyl alcohol for oscillation extraction to obtain a methyl alcohol extracting liquid; (2) diluting the methyl alcohol extracting liquid through super-pure water to obtain a diluent, and performing selective extraction on the diluent through an immersion type solid phase microextraction technology to obtain a smoke sample; (3) detecting the smoke sample through a GC-MS (gas chromatography-mass spectrometer) to detect the smoke sample, and detecting the content of the 16 polyaromatic hydrocarbons through an internal standard quantification method. The method can be used for simultaneously measuring the content of the 16 polyaromatic hydrocarbons in the mainstream smoke of the cigarettes by the GC-MS method, has the advantages of high detection speed, high sensitivity, high selectivity and high precision and is suitable for measurement of the content of polyaromatic hydrocarbon in smoke of low-tar cigarettes.

Description

technical field [0001] The invention belongs to the technical field of detection of polycyclic aromatic hydrocarbons, and in particular relates to a method for simultaneously measuring 16 kinds of polycyclic aromatic hydrocarbons in mainstream smoke of cigarettes. Background technique [0002] Smoking is harmful to health. The health hazards of cigarettes are mainly caused by harmful substances in smoke. It is the duty-bound responsibility of the tobacco industry to detect and control the release of harmful components in smoke. Polycyclic aromatic hydrocarbons are the main harmful substances in smoke, which have carcinogenic and teratogenic effects on the human body. Due to the complex composition of smoke, and the content of polycyclic aromatic hydrocarbons in smoke is trace, basically at the level of ng / cigarette, the matrix interference is serious, and the detection is difficult. Therefore, researchers often only focus on cigarette smoke. The content of the most toxic be...
