The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
using the ‘total error’ approach, applying accuracy profiles and conforming to ISO17025. None of the analysed samples exceeded the legal limit for the total amount of ∆9- THC present. However, of the 20 ...
Spectroscopic approaches for conformity analysis of e-liquids
taurine, vitamin E and CBD in e-liquids. Therefore a set of 236 e-liquids was selected. Since samples with caffeine, taurine, CBD and vitamin E as additives were hard to find, some of the samples were split ...
Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.
screening of e-liquid samples to check their compliance to the TPD i.e. non-nicotine labeled e-liquids should not contain nicotine and the maximum nicotine concentration of nicotine-labeled e-liquids should ...
Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids
chromatography (HS- GC) analysis is presented as an excellent method for the analysis of high volatile components in e-liquids. For the analysis of semivolatile ingredients, an additional sample preparation step ...
Impact of the revised European Tobacco Product Directive on the quality of e-cigarette refill liquids in Belgium
decreased over time. Before the revised TPD came into force, almost half of the samples was not conform in contrast to less than 15% non-conformities observed in the period 2017-2018. Moreover, also the ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
issue, a proper sample preparation is needed, to improve the life span of the column and reduce the total number of cuts in the GC-column. The aim of our study is to quantify potential harmful flavourings ...
