The utility model relates to a tobacco heating is volatility aroma components entrapment device and detecting system down, the entrapment device includes: pyrolytic reaction pipe (12), heating module and gaseous entrapment module (5), the heating module is established at pyrolytic reaction pipe (12) on every side for heat in order to carry out pyrolytic reaction tobacco sample (8) to placing in pyrolytic reaction pipe (12), and the one end of pyrolytic reaction pipe (12) lets in reaction gas, and the other end links to each other with gaseous entrapment module (5), and gaseous entrapment module (5) are used for collecting the volatility aroma components behind the pyrolytic reaction. The utility model discloses a more tobacco sample can be placed to the entrapment device in the pyrolytic reaction pipe to each the micro - composition among the aroma components is convenient for detect by the aroma components of the more volume of entrapment under the non - fired state of tobacco sample heating, the utility model discloses a detection method is through adopting the gas chromatography mass spectrometry method, can make to possess higher accuracy to the qualitative detection of each composition among the aroma components. |
