  • Parallel ion parking in ion traps
    Patent number: 8334503
    Abstract: A method of controlling ion parking in an ion trap includes generating a trapping field for trapping cations and anions, and applying a tailored waveform during a period when ion/ion reactions occur to park first generation product ions with m/z values that differ from those of a cation and an anion in selected m/z regions. In particular, the tailored waveform inhibits simultaneously the reactions of ions of disparate m/z ratios.
    Type: Grant
    Filed: May 1, 2006
    Date of Patent: December 18, 2012
    Assignee: Purdue Research Foundation

  • Packaging cushion and packaging assemblies incorporating same
    Patent number: 6520332
    Abstract: A packaging cushion is disclosed for supporting and protecting objects during shipment. The cushion has upper and lower surfaces and one or more compartments for supporting the objects in positions so that the objects are higher than the lower surfaces of the cushions. The cushions may include upper and lower nodes which increase the separation distance between the objects when the cushions are stacked one on top of another. The cushions may be held in a stack by an outer box, or by wrapping the stack of cushions in a protective film, eliminating the need for an outer box.
