METHOD FOR MEASURING ALUMINUM RELEASE AMOUNT IN SMOKE OF HEAT-NOT-BURN CIGARETTE

WIPO Patent Application WO/2020/253561

A1

A method for measuring an aluminum release amount in smoke of a heat-not-burn cigarette, comprising the following steps: preparing an aluminum element standard working solution; obtaining an aluminum element standard working curve according to the aluminum element standard working solution; smoking a heat-not-burn cigarette, and collecting full smoke components of the heat-not-burn cigarette; obtaining a sample preparation solution according to the collected full smoke components; and determining, according to measuring analysis of the sample preparation solution, an aluminum release amount in the full smoke components by combining the aluminum element standard working curve. Smoking of the heat-not-burn cigarette and collection of the full smoke components are performed by using a linear smoking machine (1) without needing a special smoking machine for the heat-not-burn cigarette; collection of the full smoke components is implemented by connecting multistage absorption bottles (3) in series, and measurement of the aluminum release amount is performed. The present invention is simple and high efficient, and good in stability, and has advantages of good linear correlation, good practicality, high sensitivity, and good repeatability.
