Spectroscopic approaches for conformity analysis of e-liquids
from, as well as the presentation as “the healthier option” and cost-effectiveness, it’s no wonder that e-liquids have become increasingly popular in the last 20 years, particularly with younger people. ...
Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.
spectroscopy Nicotine RAMAN Abstract: E-cigarette have become a popular alternative to smoking tobacco cigarettes. They are sold in vapeshops and online. However, in Belgium, it is prohibited to import or to buy ...
Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids
Volume 34, Issue 6, Number 230 (2021) Keywords: e-cigarettes flavours GC-MS genotoxicity Abstract: During the past decade, e-cigarettes have become increasingly popular. To guarantee their safe use and to ...
Identification of flavouring substances of genotoxic concern present in e-cigarette refills
Publication Type: Peer reviewed scientific article Authors: Sophia Barhdadi; Birgit Mertens; Melissa Van Bossuyt; Jolien Van de Maele; Roel Anthonissen; Michael Canfyn; Patricia Courselle; Rogiers, ...
Impact of the revised European Tobacco Product Directive on the quality of e-cigarette refill liquids in Belgium
caffeine and taurine, and the flavours diacetyl and acetylpropionyl. Results: Although not all manufacturers manage to produce and label their products accurately, nicotine labelling discrepancies have ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
users safety, analytical characterization of the refill liquids (e-liquids) used for e-cigarettes is essential. Different techniques have been used for the qualitative and quantitative chemical ...
Genotoxic evaluation of the liquids present in electronic cigarettes
performed with flavouring substances that have previously been identified in e-liquids. First, the genotoxic potential of these compounds was assessed using in silico prediction software Derek and Sarah ...
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 ...
Spectroscopy and Chemometrics for Conformity Analysis of e-Liquids: Illegal Additive Detection and Nicotine Characterization
glycol, glycerin, flavorings and nicotine, though there have been reports of non-compliant nicotine concentrations and the presence of illegal additives. This study explored spectroscopic techniques to ...
