Abstract
The invention discloses a method for evaluating the aerosol mass of electronic cigarettes, comprising the following steps: (1) Measurement: an electronic cigarette is smoked to measure the particle size distribution and the particle numbers in the generated aerosol, and measure the volume flow rate C of the aerosol and the testing time t; (2) Data processing: based on the particle size distribution and number, the aerosol particles are classified with classifying diameter di, and the corresponding average number concentrations n of the particles to classifying diameters di are calculated; and (3) the generated aerosol mass is calculated according to the calculation formula for the aerosol mass of the invention.
