Latest Patents

Schwartz's latest patents include a solution-cathode glow discharge mass spectrometry (SCGD-MS) apparatus. This innovative apparatus comprises a SCGD source and a mass spectrometer. The SCGD source may consist of conductive rods, a power source, and a capillary. A method for ionizing an analyte involves flowing an electrically conductive liquid onto a conductive rod and applying an electric potential to a second conductive rod. This process creates a plasma discharge that produces ions, which are then separated in a mass spectrometer. The analyte can be a polypeptide that may be contacted with trypsin, and it can exist in various states such as solid, liquid, gas, or ion in solution. Additionally, the method may include sequencing the polypeptide. Another patent focuses on a solution-cathode glow discharge (SCGD) spectrometry apparatus, which also comprises an SCGD source and a mass or ion mobility spectrometer. This method for ionizing a molecular analyte involves contacting the analyte with a plasma discharge to form ions, which are subsequently separated in a mass spectrometer or ion mobility spectrometer.
