摘要： Method and apparatus of controlling an ion population to be analyzed in a mass analyzer. Ions are accumulated for an injection time interval determined as a function of an ion accumulation rate and a predetermined desired population of ions. The accumulation rate represents a flow rate of ions from a source of ions into an ion accumulator. Ions derived form the accumulated ions are introduced into the mass analyzer for analysis.

摘要： An ion transfer arrangement for transporting ions between higher and lower pressure regions of the mass spectrometer comprises an ion transfer conduit 60. The conduit 60 has an inlet opening towards a relatively high pressure chamber 40 and an outlet 70 opening towards a relatively low pressure chamber. The conduit 60 also has at least one side wall surrounding an ion transfer channel 115. The side wall includes a plurality of apertures 140 formed in the longitudinal direction of the side wall so as to permit a flow of gas from within the ion transfer channel 115 to a lower pressure region outside of the side wall of the conduit 60.

摘要： An ion transfer arrangement for transporting ions between higher and lower pressure regions of a mass spectrometer includes an electrode assembly (120) with a first plurality of ring electrodes (205) arranged in alternating relation with a second plurality of ring electrodes (210). The first plurality of ring electrodes (205) are narrower than the second plurality of ring electrodes (210) in a longitudinal direction, but the first plurality of ring electrodes have a relatively high magnitude voltage of a first polarity applied to them whereas the second plurality of ring electrodes (210) have a relatively lower magnitude voltage applied to them, of opposing polarity to that applied to the first set of ring electrodes (205). In this manner, ions passing through the ion transfer arrangement experience spatially alternating asymmetric electric fields that tend to focus ions away from the inner surface of the channel wall and towards the channel plane or axis of symmetry.

摘要： A method of transporting gas and entrained ions between higher and lower pressure regions of a mass spectrometer comprises providing an ion transfer conduit 60 between the higher and lower pressure regions. The ion transfer conduit 60 includes an electrode assembly 300 which defines an ion transfer channel. The electrode assembly 300 has a first set of ring electrodes 305 of a first width D1, and a second set of ring electrodes of a second width D2 (≥D1) and interleaved with the first ring electrodes 305. A DC voltage of magnitude V 1 and a first polarity is supplied to the first ring electrodes 205 and a DC voltage of magnitude V 2 which may be less than or equal to the magnitude of V 1 but with an opposed polarity is applied to the second ring electrodes 310. The pressure of the ion transfer conduit 60 is controlled so as to maintain viscous flow of gas and ions within the ion transfer channel.

摘要： Sample excitation apparatus for a spectrometric analyser, the apparatus comprising a sample introduction stage comprising an electrospray nebuliser for generating a nebulised sample; and a sample excitation stage arranged to operate in an atmospheric pressure environment and to receive and excite the nebulised sample in a sample excitation region for spectrometric analysis thereof. 'Excitation' includes ionisation in ICP and MIP, flame excitation in AES, and optical excitation in AAS. For example, analyte solution (38) is fed out of the outlet end of a capillary (30,40,60,96), to a plasma source. A potential difference is applied between the capillary, its outlet end or the analyte solution and an opposing effective (counter) electrode, which may comprise a tube (64), a grid (80), or the plasma (34) itself, to promote formation of smaller droplets (46). The pressure of the plasma source is similar to the pressure in the region of the capillary outlet end.
