Deepening of In Silico Evaluation of SARS-CoV-2 Detection RT-qPCR Assays in the Context of New Variants

COVID-19 diagnosis is the detection of viral RNA by RT-qPCR with a specific set of primers and probe. It is important to frequently evaluate the performance of these tests and this can be done first by an in ...

Chemical and toxciological characterization of e-liquid cigarettes

e-liquid refills. First, a comprehensive literature search was performed to obtain an overview about the chemical composition of the e-liquids and the analytical methods used for their detection. Although the ...

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 ...
