Spectroscopic approaches for conformity analysis of e-liquids
modelling. Next to baseline correction, classical preprocessing techniques like standard normal variate (SNV), derivatives and scaling were explored. In a first step, supervised modelling, using partial least ...
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 ...
Genotoxic evaluation of the liquids present in electronic cigarettes
immunological responses in animal models. Whether these findings are also relevant to humans remains unclear. [Aim] The genotoxic potential of flavouring substances present in e-cigarettes was studied using ...
Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
investigated in silico with two complementary (quantitative) structure-activity relationship ((Q) SAR) models (Derek Nexus, Sarah Nexus). In total, 57 flavouring components were identified with a structural ...
Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.
combined with the appropriate chemometric techniques. The presented techniques do not need sample preparation and result in models with a minimum of false negative samples. If a large enough training set can ...
Spectroscopy and Chemometrics for Conformity Analysis of e-Liquids: Illegal Additive Detection and Nicotine Characterization
carefully selected for analysis. Chemometric analysis was applied to the collected data, which included mid-infrared (MIR) and near-infrared (NIR) spectra. Supervised modeling approaches such as partial least ...
