Mass spectrometer using gastight radio frequency ion guide

The disclosure relates to a mass spectrometer, comprising (a) a vacuum recipient containing ion handling elements of the mass spectrometer, the vacuum recipient having a plurality of walls which define a gastight volume and comprise at least one of an entrance and exit, wherein different portions of an ion path pass at least one of the entrance and exit and run through the gastight volume; and (b) a gastight radio frequency ion guide having an ion passage along an axis and being mounted gastight to at least one of the entrance and exit as to continue the ion path in its ion passage outside the gastight volume. Embodiments of the disclosure facilitate, in particular, reducing pumping volumes in the mass spectrometer and corresponding pumping requirements as well as lowering the size and weight of such an assembly.. ...

Mass spectrometer comprising a radio frequency ion guide having continuous electrodes

The invention relates to a mass spectrometer, comprising an ion guide having a plurality of electrodes that are supplied with a radio frequency voltage to facilitate radial confinement of ions in an internal volume defined by inward facing surfaces of the electrodes, the internal volume including a first section having a variable radial diameter along a longitudinal axis of the ion guide, in which the electrodes are helically wound, and an adjacent second section having a substantially constant radial diameter along the longitudinal axis, wherein the electrodes extend from the first section to the second section continuously. The continuous nature of the ion guide electrodes facilitates in particular unhindered axial propagation of ions through the assembly and prevents ion losses during their transmission through different compartments of the mass spectrometer.. ...

Triple quadrupole mass spectrometry coupled to trapped ion mobility separation

The invention provides a method for acquiring fragment ion spectra of substances in complex substance mixtures wherein a trapped ion mobility spectrometer (“tims”) is used as the ion mobility separation device coupled to a triple quadrupole mass filter assembly. The fragment ion spectra may be used for the identification of high numbers of proteins in complex mixtures, or for a safe quantification of some substances, by their fragment ion mass spectra in a mass spectrometer with upstream substance separator. ...
