  • Patent number: 11808741
    Abstract: A system and method for performing field-portable GC/MS measurements for the rapid sampling and measurement of high temperature boiling semi-volatile organic compounds in environmental samples, wherein other column bundles have cold spots that may prevent high temperature boiling semi-volatile components from eluting the GC column, this new design may eliminate those cold spots on the GC column.
    Type: Grant
    Filed: January 6, 2023
    Date of Patent: November 7, 2023
    Assignee: PERKINELMER U.S. LLC

  • Patent number: 11255827
    Abstract: Certain configurations described herein are directed to gas chromatography devices. In some instances, the gas chromatography devices may comprise at least one heating device which can be moved along a chromatography column to provide a thermal gradient to the chromatography column. In other instances, the gas chromatography devices may comprise a heating device that can receive a moving chromatography column to provide a thermal gradient to the chromatography column. The gas chromatography devices may be configured as portable devices which can be used to perform remote analyses.

  • Patent number: 9053919
    Abstract: A scaled down version of a toroidal radio frequency (RF) ion trap mass analyzer operating with RF trapping voltages on the order of 1 kVp-p yet despite the reduced dimensions, retains roughly the same ion trapping volume as conventional 3D quadrupole ion traps, wherein the curved geometry enables construction of a compact mass analyzer and easy interface with conventional electron multipliers.
