Detecting method for content of tar and carbonic oxide in cigarette mainstream smoke

Abstract

The invention discloses a detecting method for the content of tar and carbonic oxide in cigarette mainstream smoke. The detecting method provided by the invention comprises the followings: under nonstandard barometric pressure, collecting data for tar content regression analysis and about a cigarette sample through a LINEST function, obtaining a tar content regression equation of the cigarette sample and adjusting the tar content in the smoke of the cigarette sample; under the nonstandard atmosphere, collecting data for carbonic oxide content regression analysis and about the cigarette sample through the LINEST function, obtaining a carbonic oxide content regression equation of the cigarette sample and adjusting the carbonic oxide content in the smoke of the cigarette sample. According to the invention, a correcting relationship between analysis results of smoke inside a laboratory at the barometric pressure of 90 kPa and 100 kPa is established, through correction to the results, the accuracy and the comparability of analytic data inside a cigarette detecting laboratory can be improved, and the method plays important guiding significance on product design and cigarette box labeling in tobacco industry enterprises.

Description

technical field [0001] The invention belongs to the technical field of cigarette quality detection, in particular to a method for measuring the amount of tar and carbon monoxide in mainstream smoke of cigarettes. Background technique [0002] Cigarette mainstream smoke is one of the main contents for evaluating the quality of cigarettes. As my country begins to implement the Framework Convention on Tobacco Control, the accuracy of cigarette smoke analysis has a great impact on the disclosure of smoke emissions. Cigarette pack labels in my country must mark three important chemical components: tar content, smoke carbon monoxide content and smoke nicotine content. Accurate detection of these three chemical components is an important task for tobacco testing laboratories. [0003] Since my country's geographical environment is low in the east and high in the west, nearly one-third of the tobacco testing laboratories in the country are located in high-altitude areas, and the alt...
