  • Mass spectrometry
    Patent number: 11600483
    Abstract: A method of carrying out mass spectrometry, comprising: using an electrostatic or electrodynamic ion trap to contain a plurality of ions, each ion having a mass to charge ratio, the ions having a first plurality of mass to charge ratios, each ion following a path within the electrostatic or electrodynamic ion trap having a radius; and for each of a second plurality of the mass to charge ratios: modulating the radii of the ions in a mass to charge ratio-dependent fashion dependent upon the mass to charge ratio; fragmenting the ions thus modulated in a radius-dependent fashion; and determining a mass spectrum of the ions.
    Type: Grant
    Filed: September 12, 2017
    Date of Patent: March 7, 2023
    Assignee: The University Of Warwick
    Inventors: Peter O'Connor, Maria A. Van Agthoven

  • Methods and apparatus for determining chemical composition of reservoir fluids
    Patent number: 7095012
    Abstract: Methods of analyzing formation fluids in an oilfield environment are near-infrared absorption spectroscopy. Indications of near-infrared absorptions are analyzed to determine the concentration of compounds in a formation fluid sample.
