Última Un nouvel outil dans l'identification et la quantification des dinophysistoxines (DTXs) : le couplage Chromatographie Liquide Haute Performance / Spectrométrie de masse par piégeage d'ions quadripôlaire et interface d'électro- nébulisation (CLHP/SM2) ArchiMer Mondeguer, Florence. This report presents a new method for detection and confirmed quantification of dinophysistoxins (DTXs) using high-performance liquid chromatography coupled to mass spectrometry with an ion trap and électrospray interface (HPLC/ESI/MS2). The parameters of the ESI source and ion trap spectrum analyser were optimised to provide detection of DTXs with maximum sensitivity. These improvements were obtained after reverse-phase separation on a C18 column, with a first elution to 0.1% TFA (75:25, v/v) in isocratic acetonitrile/water mode without flow split at a column flow rate of 200 µl/min for 15 min. A second elution gradient step was added to allow optimised processing of long series of analyses without signal obstruction. This method was validated...
