摘要： A data compression technique is disclosed for Fourier Transform Mass Spectrometry (FTMS). A statistical analysis is applied to the data in the frequency domain since most of this data is a result of randomly distributed electronic noise. A fit of the whole frequency dataset to the distribution is made to determine preliminary moments of the distribution. The data in the tail of that distribution (which is mainly the peak data) is then removed and the remaining data points are re-fitted to the distribution, to identify the moments of distribution of that remaining noise data. A noise threshold for the mass spectrum is then applied using the calculated moments. The data above the threshold is kept. The whole spectrum can be reconstituted by storing the moments of distribution along with the peak data and then regenerating the noise from those moments and adding it to the peak data.

摘要： This invention relates to a method of trapping ions and to an ion trapping assembly. In particular, the present invention has application in gas-assisted trapping of ions in an ion trap prior to a mass analysis of the ions in a mass spectrometer. The invention provides a method of trapping ions in a target ion trap of an ion trapping assembly that comprises a series of volumes arranged such that ions can traverse from one volume to the next, the volumes including the target ion trap, whereby ions are allowed to pass repeatedly through the volumes such that they also pass into and out from the target ion trap without being trapped. Potentials may be used to reflect the ions from respective ends of the ion trapping assembly. Optionally, a potential well and/or gas-assisted cooling may be used to cause the ions to settle in the target ion trap.

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.
