Online analysis and detection device and method for heated cigarette smoke

Abstract

The invention discloses an on-line analysis and detection device and method for heated cigarette smoke. The device comprises a cigarette holder, a cigarette smoking module, an on-line sampling module, an on-line internal standard introduction module, an on-line smoke analysis module, a flow path system and a control module. The cigarette holder, the cigarette smoking module, the on-line introduction internal standard module and the on-line smoke analysis module are communicated with the on-line sampling module through the flow path system, and the on-line introduction internal standard module is further used for being communicated with external carrier gas; the on-line sampling module is used for collecting a smoke sample and introducing the smoke sample into the on-line smoke analysis module; the on-line internal standard introduction module is used for collecting an internal standard gas sample and introducing the internal standard gas sample into the on-line flue gas analysis module; and the on-line smoke analysis module is used for receiving the smoke sample and the internal standard gas sample to carry out smoke on-line analysis and detection. Internal standard gas is quantitatively introduced into the on-line flue gas analysis module through the on-line internal standard introduction module, so that the sample introduction amount can be ensured to be accurate, and the detection precision is improved; the smoke sample does not need to be subjected to any sample pretreatment, and simplicity, convenience and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of on-line analysis of heated cigarette smoke, in particular to an on-line analysis and detection device and method for heated cigarette smoke. Background technique [0002] In recent years, heated tobacco product (HTP) uses an external heat source to heat the cut tobacco (200-350°C) instead of directly burning the cigarette, which reduces the harmful components produced by the high-temperature (up to 900°C) combustion and cracking of tobacco. It is most similar to traditional cigarettes and is favored by consumers. [0003] Smoke is the most important characteristic of tobacco products for consumers, and the most important factor reflecting the quality level and style characteristics of tobacco products. The analysis of the chemical components of smoke is a very important basic research work. Heating cigarettes that generate aerosols by heat distillation may contain less tobacco pyrolysis and combustion de...
