Embodiment

[0029] In a cigarette of a certain brand with silica-alumina molecular sieve as the cigarette filter additive, the content of aluminum element in the silica-alumina molecular sieve sample is 3.76%. In this embodiment, Al is selected as the target element.

[0030] ①Cigarette preparation: The cigarette samples used were sorted by weight and draw resistance. The cigarettes with 5mg / cigarette solid additives added to the filter were used as experimental cigarette samples, and the cigarettes without solid additives added to the filter were used as control cigarette samples.

[0031] ②Collection of particulate matter in the flue gas: the cigarettes are smoked by the smoking machine according to the GB / T19609-2004 standard, and then the particulate matter in the mainstream smoke is collected by an electrostatic collector. The working voltage of the electrostatic collector is 17kV.

[0032] ③Sample pretreatment: elute the particulate matter collected in the electrostatic trap with 40m...

Abstract

The invention discloses a method for measuring the transfer rate of a solid filter tip additive of a cigarette in main stream smoke, and the method comprises the following steps: selecting a component element in the solid filter tip additive of the cigarette as a target element; collecting particle-phase substances in the main stream smoke of the cigarette by utilizing an electrostatic catcher; and measuring the content of the target element in the collected particle-phase substances by adopting an inductive coupling plasma mass spectrometry, thereby realizing the quantitative detection of the transfer rate of the solid filter tip additive of the cigarette in the main stream smoke and further judging the possibility that the solid filter tip additive of the cigarette escapes along with air current and is sucked into a human body. The method disclosed by the invention is accurate, reliable, simple and convenient and has important guide values in the development of the solid filter tip additive of the cigarette.

Description

technical field [0001] The present invention relates to a method for measuring the cigarette filter additive that escapes with the smoke and is inhaled into the human body, in particular to a method for measuring the transfer rate of the cigarette solid filter additive in the mainstream smoke. Potential for airflow to escape and be inhaled. Background technique [0002] Smoking has become a social and medical problem that people generally pay attention to. All countries in the world are actively conducting research on reducing harmful substances in tobacco. The use of improved filters containing additives is an important means of cigarette harm reduction. According to different types of additives, improved filters can be mainly divided into activated carbon filters, aluminosilicate filters, biological additive filters and catalyst filters. Currently, improved filters account for about 10% of the cigarette market share. Some of the different filter additives used above are...
