Embodiment 1

[0026] Under the same raw materials and process conditions, the quality trend analysis of the full-spectrum molecular spectrum is carried out on the smoke quality of the same brand of cigarettes:

[0027] a. The source and preparation of smoke samples, in accordance with the regulations of GB / T19609-2004, connected with RM20H smoking machine, ISO mode captures the total particulate matter of 20 cigarettes of Yunyan (Ruan Ruyi) brand, after the cigarettes are smoked, Inhale 2 puffs, take out the trap, let it stand for 3 minutes, use a disc-shaped glass fiber filter to capture the total particulate matter in the mainstream cigarette smoke, and put the glass fiber filter that has captured the total particulate matter in the mainstream smoke Fold it and put it in a 200mL round bottom flask to be tested.

[0028] b. The near-infrared spectrum (780-2500nm) of the sample is collected. Before the collection, the spectrometer is turned on and preheated for 2 hours. Put the cloud smoke...

Embodiment 2

[0034] Repeat Example 1, with the following differences:

[0035] a. Experimental samples Choose cigarette samples of different brands, connect to a linear smoking machine, capture the total particle phase of 20 cigarettes of Yunyan (Purple) brand in ISO mode, and collect the spectral data information of each spectrum segment respectively.

[0036] b. Use SIMCA-p11.5+ data processing software to process the collected full-spectrum spectral data of the Yunyan (purple) filter. Such as image 3 , it can be seen from the figure that for the smoke quality characteristics of Yunyan (purple), the sample distribution in the class model is relatively uniform, except for one sample, all other samples are distributed in the ellipse of the first principal component and the second principal component , which proves that the product quality is uniform and the trend is stable, and the two principal components [t1] and [t2] can explain most of the information of the brand's smoke quality cha...

Abstract

The invention discloses a cigarette smoke quality trend analysis method based on the whole spectral region molecular spectrum.The total peculate matter of 20 cigarettes with the same brand is captured through a glass fiber filter disc, near infrared spectrum data, image and spectroscopic data, ultraviolet spectrum data and Raman spectrum data of the filter disc are acquired after capture, and the whole spectral region spectrum of acquired smoke is processed with SIMCA-p11.5+ data processing software.The method is simple and easy to implement, the analysis process is quick, the calculation result is accurate, and the defects of traditional methods that the information source is not comprehensive enough and the information acquisition method is not convenient enough can be effectively overcome.Online batch operation can be achieved, and the method is well integrated with technology.The repeatability and stability of an information acquisition method are high.Production of cigarette-making enterprises can be effectively served, and favorable technical support is provided for guaranteeing cigarette smoke quality and production stability.

Description

technical field [0001] The invention belongs to the field of quality control of cigarette products, and in particular relates to a method for collecting full-spectrum molecular spectra of Cambridge filters, combined with principal component analysis and HotellingT 2 Statistical methods for the analysis of trends in the quality of cigarette smoke. Background technique [0002] With the improvement of cigarette level and the implementation and continuous advancement of the lean R&D strategy, the issues and tasks of quality improvement, consumption reduction, and efficiency increase faced by cigarette industry enterprises have become increasingly tense and urgent. Continuously improving the quality of products is the fundamental guarantee for enterprises to participate in comprehensive competition under the new economic normal. Under the new historical conditions, quality has new manifestations in its connotation and extension, that is, the stability and continuous improvement...
