The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
In Belgium, CBD-containing e-liquids with a total THC content lower than 0.2% (w/w) are currently legal. In order to verify the compliance of the different CBD-containing e-cigarette liquids that are ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV
potential for abuse and lack of the typical psychoactive effects associated with the use of cannabis products containing high levels of ∆9-tetrahydrocannabinol (∆9- THC). In Belgium, CBD-containing e-liquids ...
Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids
comply with the notification requirements of the EU Tobacco Product Directive, the EU member state regulatory authorities need information about the exact composition of the e-liquids and their emissions. ...
Impact of the revised European Tobacco Product Directive on the quality of e-cigarette refill liquids in Belgium
enough to assure the quality. Therefore, extra criteria were also assessed based on TPD requirements. Methods By using in-house validated methods, a total of 246 e-liquids purchased prior (2013-2015), ...
Identification of flavouring substances of genotoxic concern present in e-cigarette refills
have become very popular, a trend that has been stimulated by the wide variety of available e-liquid flavours. Considering the large number of e-liquid flavours (>7000), there is an urgent need to ...
A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD
(e-liquids). Currently, the most important quality indicator of e-liquid products is the quantification of nicotine and its related impurities. Although different methods have been published to measure nicotine ...
Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills
analytical methods have been published for determining e-liquid compositions, but concerns exist with respect to the lack of analytical evaluation. Hence in this study, a new HS / GC- MS-based method was ...
