  • Ionization within ion trap using photoionization and electron ionization
    Patent number: 9570282
    Abstract: A mass spectrometer is disclosed. The mass spectrometer may include an ion trap configured to trap and analyze an ionized sample. A first aperture may be provided having a first diameter, and a second aperture may be provided having a second diameter. The first aperture may be configured to receive electrons for the purpose of ionizing sample ions within the ion trap. The second aperture may be configured to receive photons for the purpose of ionizing sample ions within the ion trap.
    Type: Grant

  • REDUCED PRESSURE LIQUID SAMPLING
    Publication number: 20140190245
    Abstract: Processing a liquid sample (204) having an analyte (206) by reducing a pressure in a container (200) including the liquid sample to less than atmospheric pressure and maintaining a reduced pressure in the container. Reducing the pressure in the container (200) and optionally agitating the liquid sample increases an amount of vapor-phase analyte (206) above the liquid sample. In some cases, a concentration of the vapor-phase analyte is further increased, for example, with a chemical trap (502). The vapor-phase analyte can be provided to a chemical analyzer (302).
