Experimental Method of Emission Generation Calibration Based on Reference Liquids Characterization

Introduction:
This text provides an in-depth analysis of the impact of e-liquid composition on the mass of vaporized e-liquid (MVE) in electronic cigarettes. The study includes experiments that examine the influence of the supplied power on four pure liquids, the inhalation profile, and the effect of e-liquid composition on MVE. The authors also propose a calibration method for emission generation that can be used for Tobacco Product Directive notifications.

Key Points:

* The study examines the impact of e-liquid composition on MVE using a Cubis 1 W clearomiser and a standard protocol for electronic cigarette emission generation.
* The authors test 20 reference materials, including pure propylene-glycol, glycerol, ethanol, and water, and their mixtures.
* The study measures the density of the reference materials and compares it to the theoretical density using Equation (1).
* The authors then use the reference materials to calibrate emission generation and measure the MVE of 800 commercial e-liquids.
* The study compares the vaporization behavior of reference and commercial liquids and evaluates the performance of the proposed experimental method.

Main Message:
The study highlights the importance of e-liquid composition on MVE and proposes a calibration method that can be used for emission generation in electronic cigarettes. The proposed method is simple, practical, effective, and fast and can be easily developed in laboratories. By using reference materials with known compositions, the method can validate emission generation results, ensuring the accuracy and reliability of e-cigarette testing. Overall, the study provides valuable insights into the regulatory matters related to electronic cigarettes and emphasizes the need for standardized methods for emission generation testing.
