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 ...

Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes

chromatography–tandem mass spectrometry (UHPLC- MS / MS). A modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) procedure with the extraction by acetonitrile and purification by sodium chloride (0.5 g) ...

Towards the use of ion mobility mass spectrometry derived collision cross section as a screening approach for unambiguous identification of targeted pesticides in food

Publication Type: Peer reviewed scientific article Authors: Séverine Goscinny; Michael McCullagh; Johann Far; De Pauw, Edwin; Eppe, Gauthier Source: Rapid Communications in Mass Spectrometry, Volume ...

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 ...

Black aspergilli: A remaining challenge in fungal taxonomy?

mass spectrometry (MALDI- TOF MS) was tested and the antifungal susceptibilities of clinical isolates were evaluated. A total of 175 strains were molecularly analyzed. Three regions were amplified (ITS, ...

Falsification of biotechnology drugs: current dangers and/or future disasters?

electrophoretic techniques, immunological assays and mass spectrometry based approaches to merely identify the content of seized samples. In addition, the difference in size (peptide vs proteins vs monoclonal ...
