Abstract

The invention discloses an infrared spectroscopic analysis method of the integral quality characteristic of mainstream smoke of cigarette. The analysis of the integral quality characteristic of mainstream smoke of a cigarette sample is completed through smoke collection, power-on and pretreatment of a vacuum infrared spectrometer, background subtraction, spectrum acquisition and data analysis. The method is suitable for the analysis and detection of the integral quality characteristic of the cigarette smoke, can directly acquire the integral spectral information of the mainstream smoke without individually trapping a granule phase part by a Cambridge filter, enhances the analysis sensitivity of the above device through the background subtraction and data preprocessing, and allows the main component score of a sample to be conveniently calculated through combining a metrological calculating technology, and the score characterizes the integral quality characteristic of the mainstream smoke of the sample. The score can be widely applied to the classification, the true and counterfeit cigarette identification and the homogenization evaluation of different samples. The whole evaluation process is fast and accurate, and is highly sensitive, and the method provides effective technical support for the quality improvement and the synergism of cigarette products and the development of new products.

Description

Technical field [0001] The invention relates to a method for analyzing the overall quality characteristics of mainstream cigarette smoke, in particular to a method for directly analyzing the overall quality characteristics of mainstream cigarette smoke by adopting a highly sensitive vacuum Fourier transform infrared spectroscopy method. Background technique [0002] Cigarette is a special consumer product that achieves its use effect through smoking, and its use performance depends on the effect of mainstream smoke on consumer sensory organs. Therefore, only by studying the overall quality characteristics of mainstream cigarette smoke, and establishing a comprehensive evaluation method for mainstream smoke quality based on this, can it more truly and comprehensively reflect the smoking performance and technical characteristics of cigarette products and contribute to the quality of cigarette products. The improvement and the development of new products. [0003] Mainstream smoke ca...
