Abstract

The invention relates to a detection device and a detection method for a heavy metal migration amount of a nano filter tip, and belongs to the technical field of physical and chemical inspection of tobacco accessories. The device comprises an air inlet, air heating chambers, a ten-way valve, a filter tip holder, a smoke trapper and a smoke sucking machine; the ten-way valve comprises a plurality of rotatable air connection ports, a fixed air connection port and a numerical control turntable; the number of the rotatable air connection ports is same as the number of the air heating chambers; each rotatable air connection port is connected with one end of one air heating chamber. The other end of each air heating chamber is connected with the air inlet; the numerical control turntable is usedto control connection of each rotatable air connection port and the fixed air connection port; and the fixed air connection port, the filter tip holder, the smoke trapper and the smoke sucking machine are connected sequentially. The detection device has the advantages of simple structure, convenient operation and reducing of the influence of complex smoke, and can be used as a new analytical technique and method for heavy metal migration amount of the nano-filter tip.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing of cigarette auxiliary materials, and in particular relates to a detection device for the migration of heavy metals in nano-filters. At the same time, the invention also relates to a detection method using the detection device. Background technique [0002] Ni, Pb, Cd, Cr and other heavy metal elements in cigarette mainstream smoke are harmful substances in Hoffman list cigarette smoke. my country's proposals for the regulation and disclosure of tobacco products include Ni, Pb, Cd, and Cr in the mainstream smoke of cigarettes. During the smoking process of cigarettes, heavy metals in cigarette smoke can easily enter the human body, accumulate in the body and cause great harm to the human body. Heavy metal elements can react with proteins and enzymes to reduce their physiological activity, interfere with normal metabolism, and have a great impact on health. Therefore, the e...
