Method for measuring migration quantity of colorant smoke in filter tip by simulating cigarette smoking

Abstract

The invention relates to a method for measuring the migration quantity of colorant smoke in a filter tip by simulating cigarette smoking, and belongs to the technical field of safety evaluation of cigarette materials. The method comprises the following steps: opening a hot-air blower, and after the temperatures of an air outlet and an air outlet are stable, wrapping a to-be-detected filter tip with an additive material of the to-be-detected filter tip or cellulose acetate fibers, and then putting the to-be-detected filter tip into a purging pipe; starting the smoking machine for smoking, air flow passing through the purging pipe in the smoking process of the smoking machine, and purging out the coloring agent capable of being migrated in the blasting beads and capturing through the catcher; after purging is completed, taking down the catcher, eluting the catcher with a mixed solution of a polar organic solvent and water as an elutriator in the direction opposite to the gas flow inflowdirection, conducting filtering, using liquid chromatography for filtrate analysis, and calculating the mobility. The method provided by the invention can truly simulate the elution of cigarette smokeflow to the filter tip, and accurately determine the migration amount of the colorant component in the filter tip to the cigarette smoke, thereby objectively evaluating the safety of the colorant inthe filter tip.

Description

technical field [0001] The invention belongs to the technical field of safety evaluation of cigarette materials, and in particular relates to a method for simulating cigarette smoking to measure the migration amount of colorant smoke in a filter tip. Background technique [0002] As consumers increasingly demand personalized cigarette products, in order to highlight the personalized characteristics of cigarette products, cigarette materials such as colored cigarette paper, colored filters, and popping beads are used in cigarette products. In particular, there were only 7 brands of popping cigarettes on the market before 2015, with a total of 16 specifications. However, the camp of popping cigarettes expanded rapidly in the following two years. There are 21 domestic cigarette brands with bead-added technology, and the cumulative number of specifications on sale has reached more than 80. Almost all China Tobacco companies have pop-bead cigarette products of different specifica...

Problems solved by technology

At present, the smoke migration of the added components of the filter is generally analyzed by lighting the cigarette and smoking it, but the burning of shredded tobacco will produce a very complicated background, which brings great interference to the determination of the trace thermal migration components.

Although there are also some reports on detection devices and detection methods for the migration of filter rod additives; but there are devices with too complicated structure, inconvenient operation, and large deviations in measurement results (such as CN201810467715.6); there is no characteristic design for colorant components. Sexual migration assay devices and capture methods (such as CN201429591Y and CN203365266U) and other issues
