Le présent document spécifie des processus et protocoles généraux pour la validation et la vérification des essais qualitatifs de dépistage des résidus de médicaments vétérinaires dans le lait à l’état liquide (lait cru, lait pasteurisé, lait UHT et lait en poudre reconstitué et concentrés de protéine de lactosérum) incluant des méthodes biologiques. Ces lignes directrices ne couvrent pas la…
Animal and vegetable fats and oils — Determination of fatty-acid-bound chloropropanediols (MCPDs) an...
This document specifies a rapid procedure for the simultaneous determination of 2-MCPD esters (bound 2-MCPD), 3‐MCPD esters (bound 3‐MCPD) and glycidyl esters (bound glycidol) in a single assay, based on alkaline catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid (PBA) prior to GC-MS/MS analysis. Glycidyl ester overestimation is corrected by addition of…
