By adopting the device, the extraction and the purification of the polyaromatic hydrocarbon in the cigarette smoke can be automatically achieved, the defects of fussy processes and steps, long elapsed time, a relatively large quantity of required solvent and the like in a conventional standard detection method are overcome, two steps of the extraction and the purification are integrated, so that the target object loss can be reduced, the operation time is shortened, and the accuracy of an analysis result is improved. Therefore, the device has a good application prospect in analysis of the polyaromatic hydrocarbon.
Description
Technical field
The utility model belongs to sample preparation technical field, is specifically related to a kind of device that extracts and purify Polycyclic Aromatic Hydrocarbons in Cigarette Smoke.
Background technology
In recent years, along with the growing interest of the public to smoking and health problem, the objectionable constituent that discharge in cigarette smoke also become the focal issue that people pay close attention to, and objectionable constituent burst size progressively becomes the basic parameter of evaluating cigarette harmfulness size.At present, relevant law has been formulated in some countries and regions such as Canadian, German, requires production of cigarettes business that the burst size of main objectionable constituent in cigarette smoke is provided.
In August, 2005, < < Framework Convention on Tobacco Control > > is formally effective in China, tobacco business faces the pressure of " smoking and health problem " and further strengthens, in pact, the Jiang Shi national governments that require of " tobacco component control and disclosure " criterion work up corresponding control regime, more strictly limit the burst size of objectionable constituent in cigarette products, simultaneously, in order to develop low harm, high-quality cigarette product, tobacco enterprise also needs an objective and accurate evaluation criterion.For this reason, these factors impel tobacco business must set up harmful constituents in cigarette flue gas standard method of analysis accurately and reliably.
In 5000 multiple compounds that identify in tobacco and flue gas, objectionable constituent only account for very small percentage, and palycyclic aromatic (PAHs) is one of them.1954, the people such as Cooper separation from cigarette smoke identified benzo [a] pyrene (BaP), and this is the harmful PAHs material of the first identifying in smoke of tobacco.Along with the development of analytical technology, carried out much research aspect the PAHs of people in analysis of cigarette flue gas, the PAHs identifying is also more and more.Comprehensive, aspect analysis PAHs, Sample Pretreatment Technique has important impact to whole analytical approach.
At present, the domestic analysis to representational PAHs material-BaP in cigarette smoke, the main gas chromatography mass spectrometry method that adopts is carried out, the sample-pretreating method process relating to mainly contains flue gas trapping, sample extraction, extract purification, scavenging solution solution, and then carry out instrumental analysis, whole process steps loaded down with trivial details, consuming time long, required solvent is more.Therefore, set up a kind of easy and simple to handlely, rapidly and efficiently, and reproducible sample-pretreating method just seems particularly important.
