Abstract

The invention relates to a method for detecting a release amount of volatile organic compounds of a nano filter tip. The method comprises the following steps: (1) determining a number of suction; (2)setting a temperature of a required heating cavity according to the number of suction; step (3), carrying out suction; and step (4), analyzing components in the nano filter tip. The method provided bythe invention avoids complex background interferences and remarkably improves the precision and accuracy of a measurement result. The method provided by the invention has a simple structure and convenient operation, reduces the influence of complex smoke, and can be used as a new analysis method for the release amount of volatile organic compounds of the nano filter tip.

Description

technical field [0001] The invention relates to a method for detecting the release amount of volatile organic compounds, in particular to a method for detecting the release amount of volatile organic compounds of a nano-filter, and belongs to the field of physical and chemical inspection of cigarette auxiliary materials. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds, VOCs) refer to volatile compounds with a boiling point between 50 and 260 °C and a saturated vapor pressure exceeding 133.32 Pa at room temperature. The existence of volatile organic compounds not only poses safety risks, but also has adverse effects on the smoking quality of cigarettes when the content is too high. therefore. Quantitative analysis of volatile organic compounds in filters is of great significance both in safety evaluation and quality control. [0003] At present, the test method for the migration of the added components of the nano-filter into the cigaret...
