  • ATMOSPHERIC PRESSURE IONIZATION COUPLED TO AN ELECTRON IONIZATION MASS SPECTROMETER
    Publication number: 20240153753
    Abstract: An atmospheric pressure electron impact ionization mass spectrometer system includes an atmospheric pressure ionization component operated at an atmospheric pressure. An electron impact ionization mass spectrometer includes an electron ionization source. An atmospheric pressure interface operates below about 10 Torr. The atmospheric pressure interface includes a source block to focus a plurality of molecules and ions from the atmospheric pressure ionization component at the atmospheric pressure into the electron ionization source which operates at a pressure below about 10?3 Torr.

  • Time-of-flight mass spectrometer assembly with a secondary flange
    Patent number: 11875984
    Abstract: A time-of-flight mass spectrometer assembly includes a flange with a vacuum chamber facing surface and an environment facing surface. The flange defines an opening that extends between the vacuum chamber facing surface and the environment facing surface. A plurality of stacked components are supported by the vacuum chamber facing surface of the flange. A secondary flange is removably secured within the opening of the flange. The secondary flange includes a vacuum chamber facing surface and an environment facing surface. A supported spectrometer component is supported by the vacuum chamber facing surface of the secondary flange such that removal of the secondary flange from the flange acts to remove the supported component from the plurality of stacked components supported by the vacuum chamber facing surface of the flange.
