Patent

CA 2692718

The applicants'teachings provide methods, systems, and apparatus useful in operating mass spectrometers and other devices incorporating multipole rod sets or other multi-electrode devices to simultaneously contain ions of both positive and negative charges through the simultaneous application to the rods or other electrodes of both radio-frequency (RF) and alternating (AC) currents.

La présente invention propose des procédés, des systèmes et des appareils qui s'utilisent dans l'exploitation de spectromètres de masse et d'autres dispositifs incorporant des ensembles de barres multipolaires ou d'autres dispositifs à électrodes multiples pour contenir simultanément des ions à charges positives et négatives par l'application simultanée de courants, aussi bien radiofréquence (RF) qu'alternatif (AC), aux barres ou aux autres électrodes.
