Latest Patents

One of his latest patents is titled "Apparatus and methods for preparation and introduction of trace samples into an ionizing detection system." This patent describes an improved sample preparation technique that includes a swab, swab holder, and solvent for the effective removal of trace chemical materials. The technique enhances the delivery of analytes into mass spectrometers (MS) or ion mobility spectrometers (IMS). It involves shaping the swab to direct a pointed analyte release area toward the instrument inlet, adding a solvent, and charging the swab to create an ionized analyte spray. The solvent may also include a chemical that serves as an internal standard or benchmark.

Another significant patent is "Fragmentation resilience energy mass spectrometry (FREMS)." This invention focuses on collecting full scans of ion chromatograms using a liquid chromatography-mass spectrometry (LC-MS) device. The device determines observed ions based on mass-to-charge ratios and identifies precursor ions by referencing an LC-MS library. This innovation enhances the accuracy of chemical analysis and improves the understanding of ion fragmentation.
