| titleOfInvention | Method for analyzing aldehyde ketone chemical components in cigarette smoke |
| abstract | The invention discloses a method for analyzing aldehyde ketone chemical components in cigarette smoke, which comprises the following steps: (A) placing the tobacco sample and the glass fiber filter disc under constant temperature and humidity for balancing for 48 hours; (B) weighing not less than 3.0g of the tobacco leaf sample obtained in the step A, placing the tobacco leaf sample into a quartz tube, heating by using infrared rays, carrying out temperature rise program heating, introducing air into the quartz tube during heating to simulate the combustion process of the tobacco leaves, stopping infrared ray heating after a period of time, introducing nitrogen into the quartz tube at a certain direction to simulate the smoldering process of the tobacco leaves, trapping chemical components in smoke by using a glass fiber filter disc, and repeatedly carrying out the steps of simulating combustion and simulating smoldering for a plurality of times; (C) putting the glass fiber filter disc into a conical flask, adding an internal standard substance, and performing ultrasonic extraction by using an organic solvent; (D) the extract was analyzed by GC-MS. The method can ensure that the using amount of tobacco shreds can exceed the tobacco leaf raw material of 4 cigarettes, and ensures accurate analysis of trace aldehyde ketone chemical components in the tobacco leaf smoke. |
