Vacuum Feedthroughs, Heating Elements, and Custom Process Heaters for Aerospace, University Research, Semiconductor, Medical and OEM Applications

BCE Flanged Gasline Heater

Electron Impact Ionization

This heater assembly is used in the electron ionization in gas chromatography and mass spectrometry to ionize and fragment analyte molecules before mass spectrometric analysis and detection.

A typical electron ionization source exposes the analyte, under vacuum to a stream of thermionic electrons produced from a resistively heated-gas weldment assembly.  Gas heated up to 450°C.  Built-in thermocouple for precise temperature control is incorporated in the gas body assembly.


  • RoHS compliant parts and components.
  • Embedded thermocouple probe as shown.
  • All dimensions shown are for reference.
  • Can be used in gas chromatography and other applications.
  • Wire length/type are customer specified.
