The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV
a method was developed for screening of 17 cannabinoids and to quantify the major cannabinoids such as CBD, CBDA, ∆9- THC and ∆9- THCA. The latter was fully validated using the ‘total error’ approach, ...
CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up
CBD content not always corresponds to the label claim. There is a pressing need to develop new analytical methods specifically developed to the assay of such oily samples. Analytical issues are, ...
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 ...
Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.
RT-qPCR methods were developed in January 2020 for initial in silico specificity evaluation and to verify whether the targeted loci are highly conserved. Now that more whole genome data have become ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
a screening and a quantification method using ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC- MS) and diode array detection (UHPLC- DAD), respectively were developed and ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market
(UHPLC- MS2) and diode array detection (UHPLC- DAD), respectively were developed and validated. These methods could be used for routine analysis and enable a more in-depth characterization of ...
Analysis of illegal peptide drugs via HILIC-DAD-MS.
most frequently encountered illegal peptides on the internet in a total run time of 35min including post gradient equilibration and online cleaning step. Combined with a previously developed RPLC-method ...
Characterization of suspected dermal fillers containing hyaluronic acid
can be used as a dermal filler. The latter frequently contains cross-linked HA. Today's methods to quantify the amount of cross-linked HA are not very specific. In this paper the development and ...
Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills
developed for the screening and quantification of diacetyl and acetylpropionyl in e-liquids. This method was fully validated using the 'total error' approach. The LOQ of the analytical method was ...
