FRAGMENTATION DE LA PERMETHRINE PAR SPECTROMETRIE DE MASSE EN TANDEM EN MODE ELECTROSPRAY. MISE EN EVIDENCE D’UN ION DE STRUCTURE DIBENZOFURYLIUM

The present work allowed us to study permethrin behavior in mass spectrometry The mass spectrum is characterized by the presence of an intense pic at m/z=183 leading to identify the presence of permethrin in a mixture. A priviliged fragmentations of ions formed have also been highlighted, showing in particular the formation of an ion with dibenzofurylium structure.
