Temperature of evaporation, liquid consumption and vapor analysis in realistic conditions.

Short Summary

Dear all,

We are introducing Dr Konstantinos Farsalinos, a well-known and respected researcher on electronic cigarettes safety/risk profile.

A previous crowdfunding campaign (https://www.indiegogo.com/projects/electronic-cigarette-liquids-analysis-evaluating-potentially-harmful-ingredients) proved to be extremely important and crucial in confirming the less harmful potential of e-cigarettes but also in identifying an avoidable risk (much smaller than smoking). That study has been already published in a peer-reviewed medical journal (http://ntr.oxfordjournals.org/content/early/2014/08/30/ntr.ntu176.abstract) and we are certain that it will contribute significantly to the development of even safer products without restricting acceptability, variability and pleasure.

Continuing our commitment for unbiased research on e-cigarettes, we are now launching a new campaign for what we consider to be THE MOST IMPORTANT aspect in e-cigarette safety and future development: TEMPERATURE OF EVAPORATION. Although e-cigarettes do not combust any material, heat is necessary to generate the vapor (aerosol) which is subsequently inhaled by the users. This can result in thermal decomposition of some e-cigarette ingredients, releasing potentially toxic chemicals (most commonly aldehydes, such as formaldehyde, acetaldehyde and acrolein). Until now, no study has systematically evaluated temperatures inside the wick, while we have observed several methodological mistakes in assessing aldehydes release (e.g. ingoring that higher wattage is associated with less puff duration in realistic use). Our team has initiated this research, and has already completed preliminary experiments evaluating temperature of evaporation in realistic settings, by introducing a sensor inside the wick, and by having the atomizer fully assembled and used by a vaper.
