Description
Technical field
The invention belongs to tobacco smoke analysis field, particularly the online tobacco smoke real-time analyzer of one.
Background technology
At present, the method that tobacco smoke analysis detects is a lot, when simulating the smoking behavior of people with smoke extractor, diversified drip catcher, comprise cambridge filter, precipitator, injection ram, cold solvent (cold-trap), solid adsorbent and solvent trap to be all used for collecting main flume, direct sample also can complete the direct injection analysis of gaseous component.But all there is such problem in the tobacco smoke compositional data that these methods detect: the flue gas of the object that traditional flue gas analysis method detects and actual smoking sensory evaluating smoking differs greatly, such as: there is bigger difference in the ageing flue gas of 1 minute and fresh flue gas: the particle diameter of (1) flue gas aerosol increases rapidly, the initial diameter of particle distributes between 0.01 ~ 1.0 μm, along with the prolongation of time and the reduction of temperature, particle diameter constantly increases, after flue gas at room temperature retains 10 seconds, particle diameter increases to 0.1 ~ 46 μm, mean diameter is 0.2 μm, (2) dynamic property of flue gas causes the instability of flue gas, and because the concentration of flue gas is very high, particle wherein can condense rapidly at short notice, and newborn flue gas can be down to 1/4th of its initial value in the endocorpuscular quantity of half second.Due to cohesion, flue gas particle increases rapidly, and except flue gas physical property changes rapidly, in flue gas, the kind of compound and concentration also change, as the methyl nitrite in main flume, be actually and just occur after newborn flue gas ageing 10 second.
In theory, can realize cigarette mainstream flue gas component is realized comprehensively analyzing by modern instrumental analysis means, in practical work, cambridge filter and solvent trap are that flue gas mainly traps measure, but due to the complicacy of smoke components, flue gas composition is collected, separation and Extraction, the difficulty of enrichment, the reasons such as the change of component also having flue gas ageing to cause, trapped or solvent absorption by cambridge filter, then a series of chemical extraction and compartment analysis is carried out, this Conventional Off-line formula method, experimental procedure is numerous and diverse, waste time and energy, reappearance and less stable, and unavoidably brought sample loss and personal error into, trap in addition, processing speed is slow, and process is loaded down with trivial details, causes sample ageing, can not reflect the composition of fresh smoke product, known analysis flue gas method, causes sample composition different after fresh smoke and process, and makes existing chemical analysis results can not express the result of flue gas sensory evaluating smoking completely, be namely difficult to provide sufficient reliable information with its absorption and the complicacy analyzed.It can not be one of sensory evaluating smoking's subjective assessment major reason providing theoretical foundation that analysis that Here it is detects fundamental research.
Based on above situation, how collection analysis fresh smoke becomes a New Research of cigarette smoke chemist.
