| titleOfInvention | A method and device for measuring the migration of volatile components in cigarette popping beads |
| abstract | The invention relates to a method and a device for measuring the migration amount of volatile components in cigarette popping beads, belonging to the technical field of chemical analysis and testing. The device designed by the invention can simulate the real elution situation of the popping beads filter rod by the cigarette smoke airflow, and accurately measure the migration of the volatile components added in the popping beads to the cigarette smoke. The device also includes an attached precision purge tube and a standard filter rod that can replace the pop-up beads. The specific steps for measuring the migration amount include: installing the cigarette popping beads into a standard filter rod, then pinching the popping beads and putting them into a purge pipe; using the device of the present invention to simulate cigarette smoking for purging, and using an adsorption cold trap to capture volatile After trapping, the content of volatile components is determined by gas chromatography-mass spectrometry connected to dynamic headspace; and the mobility is calculated. The device and method of the invention can meet the requirement of accurate measurement of the migration amount of volatile components in the popping beads, and provide a scientific and convenient new method for the objective evaluation of the efficacy of the ingredients added to the popping beads. |
