Sample preparation methods for elemental analysis in electronic cigarette aerosols: a critical review
e-cigarette consists of an e-liquid and a heating device, generating an aerosol that the user can inhale. Recently, several studies have shown that metals and metalloids, including As, Cd, and Pb, known ...
Evaluating MIR and NIR Spectroscopy Coupled with Multivariate Analysis for Detection and Quantification of Additives in Tobacco Products.
times, and the requirement for skilled operators. This study addresses these challenges by evaluating the efficacy of mid-infrared (MIR) spectroscopy and near- IR (NIR) spectroscopy, coupled with ...
Method Development and Validation of an Aerosol Sampling Technique for the Analysis of Nicotine in Electronic Cigarette Aerosols
the EU, the Tobacco Products Directive requires emission studies for e-cigarette products. The absence of industry guidelines for studying these emissions and the lack of proper validation in the ...
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 vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.
improvement of Raman PLS model and further SERS studies with tests on a larger number of samples are still needed. Health Topics: E-sigaret E-cigarette E-cigarette Service: Médicaments et produits de santé ...
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 ...
