Patent

CA 2585565

A mass spectrometer is disclosed comprising an ion mobility spectrometer or separator (4) and an ion guide (6) arranged downstream of the ion mobility spectrometer or separator (4). A plurality of axial potential wells are created in the ion guide (6) so that ions received from the ion mobility spectrometer or separator (4) become confined in separate axial potential wells. The potential wells maintain the fidelity and/or composition of ions received from the ion mobility spectrometer or separator (4). The potential wells are translated along the length of the ion guide (6).

L'invention concerne un spectromètre de masse comprenant un spectromètre de mobilité ionique ou séparateur (4) et un guide d'ions (6) disposé en aval du spectromètre de mobilité ionique ou séparateur (4). Une pluralité de puits de potentiel axiaux sont créés dans le guide d'ions (6) de sorte que les ions reçus en provenance du spectromètre de mobilité ionique ou séparateur (4) se retrouvent confinés dans des puits de potentiel axiaux. Les puits de potentiel assurent le maintien de la fidélité et/ou de la composition des ions reçus en provenance du spectromètre de mobilité ionique ou séparateur (4). Les puits de potentiel subissent une translation sur la longueur du guide d'ions (6).
