  • Mass Spectrometer
    Publication number: 20140322817
    Abstract: A mass spectrometer is disclosed comprising an Electron Transfer Dissociation cell. Positive analyte ions are fragmented into fragment ions upon colliding with singly charged negative reagent ions with the cell. The cell comprises a plurality of ring electrodes which form a spherical trapping volume. Ions experience negligible RF heating over the majority of the trapping volume which enables the kinetic energy of the analyte and reagent ions to be reduced to just above thermal temperatures. An Electron Transfer Dissociation cell having an enhanced sensitivity is thereby provided. Fragment ions created within the cell may be cooled and may be transmitted onwardly to an orthogonal acceleration Time of Flight mass analyser enabling a significant improvement in the resolution of the mass analyser to be obtained.

  • Mass Spectrometers Comprising Accelerator Devices
    Publication number: 20140284471
    Abstract: A method of mass spectrometry is disclosed comprising providing a flight region for ions to travel through and a detector or fragmentation device. A potential profile is maintained along the flight region such that ions travel towards the detector or fragmentation device. The potential at which a first length of the flight region is maintained is then changed from a first potential to a second potential whilst at least some ions are travelling within the first length of flight region. The changed potential provides a first potential difference at an exit of the length of flight region, through which the ions are accelerated as they leave the length of flight region. This increases the kinetic energy of the ions prior to them reaching the detector or fragmentation cell.

  • Method and System for Evaluating Target Date Funds
    Publication number: 20140222714
    Abstract: The invention generally concerns systems, methods, and apparatus wherein a computer may receive information concerning a group of target date funds from a database. Information about the target date funds may comprise information about the glide path and the target retirement date of that fund. A diversification level of each of the target date funds may be determined from the received information. An equity ratio may also be determined for each of the target date funds using the received information. In some instances, the equity ratio may be based upon the amount of equity projected to be owned by the target date fund upon the target retirement date. After determining an equity ratio and a diversification level, a summary of the group of funds is output for review by a user. The summary may include a summary or graph of the diversification levels and equity ratios of the target date funds.
