The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
Cannabinoids cannabis Chromatography, Liquid Dronabinol Electronic Nicotine Delivery Systems Mass Spectrometry Abstract: The use of cannabidiol or CBD products has skyrocketed in the last five years due to the ...
Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium
quantification of active pharmaceutical ingredients (API s) potentially present in these suspicious SF antimicrobials, are paramount. Here, a validated ultra-high performance liquid chromatography-tandem mass ...
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
quantify a wide range of antimicrobials in suspected illegal products. In this work, a screening and a quantification method using ultra-high performance liquid chromatography with tandem mass spectrometry ...
Analysis of illegal peptide drugs via HILIC-DAD-MS.
in terms of resolution and symmetry factor for the targeted peptide set. Hence, the operational conditions were further optimised for the identification of illegal preparations via mass spectrometry ...
Chromatographic impurity fingerprinting of genuine and counterfeit Cialis® as a means to compare the discriminating ability of PDA and MS detection.
