Spectroscopic approaches for conformity analysis of e-liquids

samples. After obtaining the data matrices, chemometric analysis was performed. For each type of data, the sample matrix was split into a training and  test set. Spectroscopic data were preprocessed before ...

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 ...

Identification of flavouring substances of genotoxic concern present in e-cigarette refills

transhexanal, there was a clear concern for in vivo genotoxicity. A selection of 4 out of the remaining 22 flavourings was tested in two in vitro genotoxicity assays. Three out of the four tested flavourings ...

Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids

to the column. Different sample clean up techniques were tested. Finally the liquid-liquid extraction (LLE) with freeze out using flash cooling technique was optimized. This sample preparation ...

Genotoxic evaluation of the liquids present in electronic cigarettes

animal-free approaches. In addition, the applicability of the Ames test and the in vitro micronucleus test to evaluate the genotoxic potential of e-liquids mixtures was investigated. [Methods]  The study was ...
