Description
Technical field
The invention belongs to tobacco detection technique field, be specifically related to the capturing device of ammonia in a kind of trapping assay method of ammonia of main stream smoke of cigarette and gas phase.
Background technology
Ammonia is naturally occurring composition in tobacco, is one of main objectionable constituent of generally acknowledging in cigarette mainstream flue gas, is the important indicator of China's evaluating cigarette harmfulness.Suitable nitrogen-containing compound content can keep the suitable physiological strength of flue gas and concentration, and ammonia content is too low, can cause that flue gas strength is little, and richness is inadequate; Can produce again strong impulse by excess of ammonia, cause the contraction of smoker throat, allow people feel to choke and cough, sensation pungent, unbearably that nasal cavity, tongue have.So the Accurate Determining of ammonia content in cigarette smoke not only be can be used for evaluating to the quality of tobacco, more importantly for the research that reduces cigarette objectionable constituent provides reference.
Ammonia of main stream smoke of cigarette is present in flue gas grain phase and gas phase, after needing respectively the ammonia in grain phase and gas phase to be collected, then carries out determination and analysis.In components in cigarette smoke gas phase, the capture method of ammonia has been realized the collection of ammonia in gas phase.
Ammonia of main stream smoke of cigarette content is to measure according to tobacco business standard (the assay method chromatography of ions of ammonia in YC/T377-2010 main flume).The method is the ammonia in mutually with cambridge filter trapping main flume grain, with hydrochloric acid solution extraction, after the trapping hydrazine trapping that in gas phase, ammonia is made with the glass material that hydrochloric acid solution is housed, pipettes respectively gas phase absorption liquid and a grain phase extract, dilution constant volume after merging.Constant volume liquid, after ion-exchange separates, adopts electric conductivity detector to measure, and is converted into the content of ammonia in main flume.
In practical operation, Shortcomings on the capture method of the method ammonia in gas phase: (1), operating efficiency is low: trapping complex operation step, program is many, more time-consuming; (2), ammonia arresting efficiency is low: pipeline is long, and junction is many, and easily gas leakage, causes ammonia in gas phase not to be completely absorbed; , because trapping is equipped with solution in hydrazine, easily cause suck-back phenomenon.
