Journal of Pharmaceutical and Biomedical Analysis, Volume 205 (2021) Keywords: Cannabidiol CBD oils GC-MS/MS MRM Sample clean up Abstract: Quality control of CBD oils on the Belgium market showed that the ...
Chemical and toxciological characterization of e-liquid cigarettes
methods were developed for the quantitative determination of nicotine and its related impurities (HPLC- DAD) and for the flavours diacetyl and acetylpropionyl (HS / GC- MS). Also, screening methods were ...
Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
genotoxic substances in e-liquid flavours. 77 e-liquids, representative for the different flavour categories, were collected on the Belgian market and screened for their chemical composition using GC- MS. By ...
Ontwikkeling en validatie van een HS-GC-MS/MS methode voor de bepaling van potentieel genotoxische smaakstoffen in e-vloeistoffen.

Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills
analytical methods have been published for determining e-liquid compositions, but concerns exist with respect to the lack of analytical evaluation. Hence in this study, a new HS / GC- MS-based method was ...
Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach
Therefore, when using a larger sample set including more possible sources of variation, more sophisticated detection techniques such as MS might be necessary. Chapter VIII describes the use of headspace- GC ...
HS-GC-MS method for the analysis of fragrance allergens in complex cosmetic matrices.
combined with a new headspace GC- MS method. The latter was capable of analysing 24 volatile allergenic fragrances in complex cosmetic formulations, such as hydrophilic (O/W) and lipophilic (W/O) creams, ...
Headspace-gas chromatographic fingerprints to discriminate and classify counterfeit medicines.
Viagra(®) and Cialis(®) samples were analyzed for residual solvent content using headspace- GC- MS. The obtained chromatograms were used as fingerprints and analyzed using different chemometric techniques: ...
A validated GC-MS method for the determination and quantification of residual solvents in counterfeit tablets and capsules.
Temperature Time Factors Abstract: A fast headspace GC- MS method was developed and validated for the detection and quantification of residual solvents of all three ICH-classes in counterfeit tablets and ...
Accuracy and reproducibility of automated estradiol-17beta and progesterone assays using native serum samples: results obtained in the Belgian external assessment scheme.
it is suggested that, for performance testing, results be compared whenever possible with a reference method. The linear relationship as assessed by comparing results with those obtained by ID- GC / MS ...
