The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
available to the Belgian population, a method was developed for screening of 17 cannabinoids and to quantify the major cannabinoids such as CBD, CBDA, ∆9- THC and ∆9- THCA. The latter was fully validated ...
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 ...

Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.
the products is not always labelled, especially when they are bought through internet. Therefore there is a need for easy-to-use equipment and methods to perform a first on site screening of intercepted ...
Spectroscopy and Chemometrics for Conformity Analysis of e-Liquids: Illegal Additive Detection and Nicotine Characterization
the efficacy of MIR and NIR spectroscopic techniques in conjunction with chemometric methods (SIMCA and PLS- DA) for detecting specific molecules in e-liquids. MIR with autoscaling data preprocessing ...
