| titleOfInvention | A method for detecting ammonia content in particulate matter in mainstream cigarette smoke |
| abstract | The invention relates to the technical field of tobacco detection, in particular to a method for detecting the ammonia content in the particulate matter of cigarette mainstream smoke, which comprises the following steps in sequence: capturing, extracting, constant volume, filtering and measuring the ammonia in the granular phase; The trapping of ammonia includes the following steps: After emptying, a puff-by-puff suction device is set between the suction source and the cigarette for puff-by-puff suction. After the smoking is completed, remove the cigarette and keep it away from the trap for smoldering; after smoldering, transfer the cigarette to the hole where the next trap is located, and repeat the above-mentioned suction and smoldering operations in sequence until the cigarette smokes. Finish sucking. Through the capture method of the present application, the amount of sidestream smoke entering the mainstream smoke can be effectively reduced, and precursors that affect the stability of ammonia can be eliminated, thereby effectively improving the stability of the ammonia detection solution and accurately measuring the mainstream smoke of cigarettes. Ammonia content in gaseous particulate matter. |
