  • Publication number: 20200271557
    Abstract: A method for providing in situ chemical transformation and ionization of a portion (e.g., inorganic oxidizer) of a sample via an analyte detection system is disclosed herein. The method includes introducing a gas into an ionization some of the analyte detection system via an inlet. The method further includes generating ions within the ionization source and directing the gas and generated ions through and out of the ionization source and to the sample. The sample is located proximal to the ionization source in an ambient environment. The ions chemically react with the sample and desorb and ionize an analytic from the sample, the analyte being generated from the inorganic oxidizer, the desorbed analyte having a lower melting point and/or better desorption kinetics than the inorganic oxidizer. The method further includes receiving the desorbed analyte via an analyzer of the analyte detection system.

  • Patent number: 10665446
    Abstract: A surface ionizer for a trace detection system includes an extreme ultraviolet light source and an ion transfer line. Activation of the extreme ultraviolet light disrupts a surface of a sample along with residue and ionizes the resulting vapor. The ionized vapor is collected in the ion transfer line and passed into an analysis device for detection of components in the vapor.

  • Patent number: 9972482
    Abstract: A concentric APCI surface ionization probe, supersonic sampling tube, and method for use of the concentric APCI surface ionization probe and supersonic sampling tube are described. In an embodiment, the concentric APCI surface ionization probe includes an outer tube, an inner capillary, and a voltage source coupled to the outer tube and the inner capillary. The inner capillary is housed within and concentric with the outer tube such that ionized gas (e.g., air) travels out of the outer tube, reacts with a sample, and the resulting analyte ions are sucked into the inner capillary. A supersonic sampling tube can include a tube coupled to a mass spectrometer and/or concentric APCI surface ionization probe, where the tube includes at least one de Laval nozzle.

  • Publication number: 20150371807
    Abstract: A surface ionization source comprises a tube having a first end, a second end, and an interior bore extending through the tube from the first end to the second end. The first end of the tube is configured to receive a flow of gas and the second end of the tube is configured to direct the flow of gas onto a surface configured to hold an analyte. A radioactive source is at least substantially disposed in the interior bore of the tube. The radioactive source is configured to form ions in the flow of gas as the flow of gas passes through the interior bore. The flow of gas containing the ions is directed onto the analyte to at least partially ionize the analyte.
