20120112051 | Atmospheric Pressure Charge-Exchange Analyte Ionization - A non-radioactive atmospheric pressure method for ionization of analytes comprises creating an electrical discharge in a carrier gas thus creating metastable neutral excited-state species. The carrier gas is directed at the analytes and the analytes under conditions to suppress protonated water and water clusters. | 05-10-2012 |
20120006983 | METHOD OF SURFACE IONIZATION WITH SOLVENT SPRAY AND EXCITED-STATE NEUTRALS - A method of producing analyte, analyte fragment, and/or analyte adduct ions for mass analysis comprises the steps of spraying a solvent at a surface bearing the analyte, directing desorbed analyte evolved from the surface into a region containing species which will ionize the analyte on collision, the ionizing region not including the surface bearing the analyte, and directing the ions formed in the ionizing region to the entrance to a mass analyzer. | 01-12-2012 |
20100291704 | Method of Inorganic Analysis by Mass Spectrometry - A method of inorganic analysis by mass spectrometry comprises treating a surface with a chelating reagent so that inorganic elements can be made volatile and desorbed directly from the surface, exposing the volume over the surface or a swab wiping the surface to a flow of metastable atoms and molecules at atmospheric pressure to ionize volatile compounds, and passing the ionized volatile compounds to a mass spectrometer or the like. | 11-18-2010 |
