Latest Patents

One of Oxley's latest patents is titled "Apparatus and methods for preparation and introduction of trace samples into an ionizing detection system." This patent describes an advanced sample preparation technique that includes a swab, swab holder, and solvent designed to effectively remove trace chemical materials from swabs. The method facilitates the delivery of these materials into a mass spectrometer (MS) or an ion mobility spectrometer (IMS). The technique involves shaping the swab to direct a pointed analyte release area toward the instrument's inlet, adding a solvent, and charging the swab to create an ionized analyte spray. This innovative approach enhances the efficiency of chemical detection.

Another notable patent is "Fragmentation resilience energy mass spectrometry (FREMS)." This invention focuses on utilizing a liquid chromatography-mass spectrometry (LC-MS) device to collect full scans of ion chromatograms from samples. The device determines the observed ions based on mass-to-charge ratios and identifies precursor ions by referencing an LC-MS library. This method improves the accuracy of
