Description
Technical field
The utility model relates to smoking material analysis technical field, the device that specifically a kind of chemisorption performance for smoking material is analyzed.
Background technology
Smoking is one of subject matter facing in tobacco business development with health.Along with growing to even greater heights and the generally enhancing of consumer to smoking and health concerns of world's Anti-smoking activity, market is more and more higher to the requirement of cigarette, make industry development be faced with a unprecedented pressure and challenge, developing " low harm " cigarette and relevant auxiliary materials is the common requirement of the public to tobacco business, is also social responsibility and obligation that tobacco business must be born.
Chemisorption is transfer, the exchange or total that electronics occurs for adsorption molecule and solid surface atom (or molecule), forms the absorption of absorption chemical bond.Because solid surface exists the inhomogeneous field of force, lip-deep atom often also has remaining bonding power, when gas molecule collision on solid surface time just and exchange, the transfer or total of electronics occur between surface atom, form the suction-operated of absorption chemical bond.How the chemisorption performance of smoking material is carried out to determination and analysis fast, and the absorption property of smoking material is passed judgment on, for the design of cigarette product provides theoretical foundation, oneself becomes important research topic at present.
Summary of the invention
The purpose of this utility model is that a kind of device of express-analysis is provided for the absorption property of Fast Evaluation smoking material, thereby improves research and development of products efficiency.
The utility model is achieved through the following technical solutions: the device of the chemisorption analysis of smoking material is connected to form successively by gas control unit, sample analysis unit, sample detection unit and tail gas treating unit; Gas control unit is comprised of gas source pipe and the gas flow valve that is arranged on gas source pipe, sample analysis unit consists of be connected in parallel sample hose and blank sample passage of a T-valve, sample detection unit consists of detecting device, and tail gas treating unit is managed device outward by tail gas and formed.
Further, between sample analysis unit and sample detection unit, be connected with filtration unit, cold-trap I, visual gas meter in turn.
Further, between sample detection unit and tail gas treating unit, be connected with cold-trap II.
The gas source pipe of described gas control unit is comprised of 1-5 group with the gas meter that is arranged on gas source pipe, and 5 groups of gas source pipe right-angled intersections arrange.
On every described gas source pipe, be provided with two gas flow valves.
Utilize said apparatus as follows to the using method of the chemisorption analytical equipment of smoking material:
By the gas configuring by carrier gas control module, by flowmeter adjusting air inflow quantity.Gas, by detected sample, then carries out thermal desorption to sample, and desorption gas detects analysis by detecting device, thereby the adsorbance of material is carried out to quantitative test, and desorption gas absorbs through processing unit.
By adjusting gas with various, the smoke components in simulation cigarette, detects analysis to smoking material to the absorption property of gas.And can, by one or more gases are mixed and joined, investigate it and detect in the desorption rate by after cigarette material, thereby for cigarette material, the adsorptive power of gas be passed judgment on.
Device of the present utility model can be analyzed the chemisorption performance of smoking material fast, and it is simple to operate, need not carry out complicated actual cigarette product preparation, can not increase the R&D costs of product.Can utilize fast analytical equipment to study the absorption property of material, thereby provide reference for production and the product development of product.
