Patent

CA 2672525

A mass spectrometer is disclosed comprising a device (2) which is operable in a first mode of operation to separate ions temporally according to their ion mobility by applying a continuous axial electric field. The device (2) is also operable in a second mode of operation wherein ions are separated temporally according to the their mass to charge ratio by pulsing an applied axial electric field ON and OFF.

L'invention concerne un spectromètre de masse comprenant un dispositif (2) exploitable dans un premier mode d'exploitation pour séparer temporairement des ions en fonction de leur mobilité par application d'un champ électrique axial continu. Le dispositif (2) est également exploitable dans un second mode d'exploitation dans lequel les ions sont temporairement séparés en fonction de leur rapport de masse et de charge par activation et désactivation d'un champ électrique axial appliqué.
