Abstract:
A system and method of mass spectrometry is provided. Ions from an ion source are stored in a first ion storage device and in a second ion storage device. Ions are ejected from the first ion storage device to a first mass analysis device during a first ejection time period, for analysis during a first analysis time period. Ions are ejected from the second ion storage device to a second mass analysis device during a second ejection time period. The ion storage devices are connected in series such that an ion transport aperture of the first ion storage device is in communication with an ion transport aperture of the second ion storage device. The first analysis time period and the second ejection time period at least partly overlap.
Abstract:
A device and associated method are disclosed for interfacing an ion trap to a pulsed mass analyzer (such as a time-of-flight analyzer) in a mass spectrometer. The device includes a plurality of separate confinement cells and structures for directing ions into a selected one of the confinement cells. Ions are ejected from the ion trap in a series of temporally successive ion packets. Each ion packet (which may consist of ions of like mass-to-charge ratio), is received by the ion interface device, fragmented to form product ions, and then stored and cooled in the selected confinement cell. Storage and cooling of the ion packet occurs concurrently with the receipt and storage of at least one later-ejected ion packet. After a predetermined cooling period, the ion packet is released to the mass analyzer for acquisition of a mass spectrum.
Abstract:
This invention relates to the analytical electronics used to identify compositions and structures of substances, in particular, to the analyzers comprising at least one mass-spectrometer (MS) and may be applied in such fields as medicine, biology, gas and oil industry, metallurgy, energy, geochemistry, hydrology, ecology. Technical result provides the increase in MS resolution capacity, gain in sensitivity, precision and measurement rates of substances compositions and structures concurrently with enhancement of analyzer functional capabilities, downsizing and mass reduction. A multipath method of mass-spectrometry and a three-dimensional reflecting (-reflecting) method of mass-spectrometry requiring to use a three-dimensional reflecting IO sub-system (- reflector) are developed. A new type of electric field distribution such as transversely discontinuous conic field distribution, including its type of three-dimensional distribution in area of reflection, is proposed to implementing said methods. Versions of devices to implement the claimed method are developed. Proposed schematic ion optical diagrams allow to developing different MS types.

Abstract:
Unité de traitement d'ions (10) comprenant une série de M feuilles d'électrode perforées (12), un système électronique de commande (14, 16) et une unité centrale (18), qui permet la formation, la mise en forme et la translation de puits de potentiel effectifs multiples (42). Des ions, piégés dans un puits de potentiel effectif donné (42), peuvent être isolés, transférés , refroidis ou chauffés, séparés et combinés. La mesure de courants d'images induits permet la mesure et le groupage d'espèces d'ions selon leur rapport respectif charge-masse. La combinaison de nombreuses feuilles d'électrode (12), chacune ayant N perforations multiples (22 ), crée une pluralité de canaux de traitement d'ions parallèles (26). Ladite unité de traitement d'ions (10) fournit un systeme de traitement d'ions massivement parallèle N par M, ce qui permet de traiter un grand nombre d'ions en parallèle de la même manière, mais avec des procédés d'ions différents selon les différentes parties de chaque canal de traitement d'ions (26). De plus, la structure parallèle occupant l'espace de la présente invention fournit un moyen efficace de stockage temporaire de grands nombres d'ions, y compris de l'antimatière chargée.
