The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
CBD-liquids investigated in this study, only 30% of the samples contained an amount of CBD that was within 10% deviation of the label claim. Moreover, the CBD e-liquids labelled “full/broad spectrum” consisted ...
Spectroscopic approaches for conformity analysis of e-liquids
Therefore, it is necessary to monitor the compositions of the products on the market and conduct surveillance studies. In Belgium this is performed under the coordination of the Federal Public Service of ...
Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids
However, one of the challenges encountered during the analysis of e-liquids is the presence of the highly abundant e-liquid matrix components propylene glycol and glycerol. In this study, headspace gas ...
Identification of flavouring substances of genotoxic concern present in e-cigarette refills
establish a screening strategy to prioritize the flavouring substances of highest concern for human health. In the present study, a prioritization strategy combining analytical screening, in silico tools and ...
Impact of the revised European Tobacco Product Directive on the quality of e-cigarette refill liquids in Belgium
containing mandatory rules to assure the quality and safety of electronic nicotine delivery systems. In this study, we investigate whether these regulatory changes had an impact on the quality of refill ...
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 ...
Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
cancer. Therefore, in this study, a prioritization strategy based on a combination of analytical screening, in silico prediction and literature consultation was developed for identifying potentially ...
