Abstract
Il s'agit d'une méthode et d'un appareil de fragmentation qui comprend une cellule de collision multipolaire RF (3) dans laquelle les ions précurseurs sont extraits et transportés à travers un guide d'ions multipolaire RF (24). Ces ions sont formés par réaction de capture des électrons avec les électrons de faible énergie engendrés dans la source d'électrons de faible énergie (5).
