Abstract

La présente décrit un spectromètre comportant une cellule de fragmentation 1 constituée d'un certain nombre d'électrodes annulaires ou en forme de plaque ayant des ouvertures à travers lesquelles les ions sont transmis. Un gradient de courant continu axial est de préférence maintenu le long d'au moins une partie de la longueur de la cellule de fragmentation T dans le but d'améliorer le temps de transit des ions à travers le dispositif.
