2014 Preliminary Aerosol Proficiency Study
EVAP Technical Report
In 2014, the CORESTA E-cigarette Task Force, now known as the E-Vapour Sub-Group, conducted a preliminary proficiency study to determine the inter-lab variability for the quantification of the major constituents of e-cigarette aerosol using specified puffing parameters to evaluate aerosol generated from a common pool of e-cigarette products. The study included determination of puff count, trapped aerosol, nicotine, propylene glycol (PG), glycerin and water. The test methods used for quantification of specific analytes were left to the discretion of participating laboratories.
The study results demonstrated that aerosol delivery for the study samples was relatively variable and that the analyte deliveries for a given product tended to be proportional to Aerosol Collected Mass (ACM) deliveries. Evaluation of analyte results normalised to ACM delivery yielded acceptable r&R values. Based on these results, a follow-up study was recommended and conducted in 2015 which resulted in CORESTA Recommended Method No. 84.
