Identification of fungal isolates by MALDI-TOF mass spectrometry in veterinary practice: validation of a web application.

Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization Veterinary Medicine yeasts Abstract: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI- TOF MS) has emerged as ...

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 ...

Pesticide residues in Tunisian table grapes and associated risk for consumer’s health

presence of 96 pesticides, including dithiocarbamates, was assessed. Pesticides identification and quantification were performed by liquid or gas chromatography, coupled to tandem mass spectrometry. All ...
