Embodiment Construction

[0027] The scheme of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 2 As shown, the analysis system of the cigarette gas phase combustion product of the present invention comprises a cracker and a thermal desorption-mass chromatography spectrometer equipped with a special thick liquid film capillary chromatographic column for volatile organic compounds (VOC) combined with the cracker (ATD-GC / MS), the cracker main body adopts SGE micro-furnace cracker (PyrojectorII), it has been transformed, and it comprises injector, air inlet chamber 10, cracking furnace chamber 7, quartz tube 6, inlet The sampler includes a sampling rod 1, which is connected to one end of the quartz tube 6 after passing through the air inlet chamber 10, the quartz tube 6 is located in the cracking furnace chamber 7, and the other end of the quartz tube 6 extends out of the cracking furnace chamber 7. Connected with the inlet of t...

Abstract

The invention provides an analysis method and system for a gas phase combustion product of a cigarette. The analysis method comprises the following steps of: putting tobacco leaf powder in an oxygen-containing gas atmosphere for cracking at the same temperature; completely cooling a cracking product, filtering particle phase constituents through a Cambridge filter; adsorbing the gas phase ingredients by adopting an adsorption sampling pipe; and performing thermal desorption on the adsorption sampling pipe, and entering a gas-mass combined spectrometer for analyzing. Correspondingly to the analysis method, a commercial SGE (Severable Government Equipment) microwave cracker is improved, so that capturing of the gas phase constituents of the cracking product is realized for the first time, and the gas phase constituents are subjected to qualitative and quantitative analysis. The analysis method and the analysis system can be used for discovering the formation mechanism of harmful ingredients in smoke, and a theoretical foundation is laid for the researches of depression of the tar and reduction in harmfulness of cigarettes.

Description

technical field [0001] The invention relates to an analysis method and analysis system for gas phase combustion products of cigarettes. Background technique [0002] The micro-furnace cracker has a simple structure, uniform temperature distribution in the furnace chamber, reliable performance, and is widely used, and is widely used in the tobacco industry. At present, this type of pyrolyzer mainly has two types of applications in the tobacco industry: the first one is directly connected to the vaporization chamber of gas chromatography spectrometer (GC / MS) and used as an online pyrolysis analysis platform, which is convenient and reliable. Good reproducibility. However, since the ordinary capillary chromatographic column cannot contact the oxygen-containing atmosphere during the heating process, the system cannot realize aerobic cracking, and the injection volume is relatively small. The other is used alone, using a cold trap to capture the cleavage product, then eluting i...
