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

mass accuracy and retention times in a pesticide screening method that integrates all the features offered by coupling ultra‐performance liquid chromatography (UPLC) with ion mobility mass spectrometry ...

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 ...

Analytical strategies for the determination of pyrrolizidine alkaloids in plant based food and examination of the transfer rate during the infusion process

chromatography and tandem mass spectrometry (MS / MS) for the determination of 30 pyrrolizidine alkaloids (PA s) in salads, herbs, tea, herbals teas as well as tea infusion and ice tea beverages. Total PA ...

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 ...

Development and validation of a quantitative UHPLC-MS/MS method for selected brominated flame retardants in food.

performance liquid chromatography — tandem mass spectrometry (UHPLC- MS / MS) method was developed and validated (in-house) for the quantification of selected brominated flame retardants (BFR s), including ...
