Abstract
A method for measuring the mobility of growth regulators and pyrethroid pesticides in heat-not-burn cigarettes growth regulator and pyrethroid pesticide residues to determine the mobility of growth regulators and pyrethroids in heat-not-burn cigarettes. The method of the present invention fills the blank of the determination of the migration of pesticide residues in heat-not-burn cigarettes. The method of the invention has the following excellent effects: the sample pretreatment process of the method of the invention is simple and fast, and has the advantages of accurate operation, high sensitivity and good repeatability.
Description
technical field [0001] The invention belongs to the technical field of physical and chemical inspection of pesticide residues, and mainly relates to a technology for determining the residues of growth regulators and pyrethroid pesticides in different materials such as cut tobacco, filter tips, and filter discs. After smoking HNB cigarettes, the levels of growth regulators and pyrethroids in HNB cigarettes during smoking were determined by analyzing growth regulator and pyrethroid residues in different parts of HNB cigarettes. Migration behavior. Background technique [0002] In recent years, the market share of HNB products has increased year by year, and the research on HNB products has gradually become a current hot spot. Heat-not-burn tobacco products use a special heat source to heat cigarette cores made of cut tobacco or other tobacco materials (150-500°C) to generate inhalable aerosols. Its heating temperature is much lower than the burning temperature of traditional...
