EPIC / EPIC 1000 Series

A system for UHV analysis of neutrals, radicals and ions

The Hiden EPIC and IDP have all the features of high performance RGAs – but with the addition of pole bias mid-axis potential and negative ion capability making them outstanding research grade mass spectrometers.

EPIC for UHV analysis of neutrals, radicals and ions


The EPIC system is factory-upgradeable for the inclusion of an energy-filter, either the Bessel box or 45 degree sector field type, ensuring compatibility with the Hiden plasma/SIMS series including the EQP, EQS, PSM and SIM probes.


  • Mass range options to 5000 amu, 6 or 9 mm pole diameter options
  • Enhanced long-term Stability (less than ±0.5% height variation over 24 h)
  • Ion Energy distribution by mid-axis potential scanning ±100 V, 1000 eV Option
  • Ion source control for soft ionisation and appearance potential mass spectrometry
  • Enhanced sensitivity for high mass transmission, Automatic mass scale alignment
  • Pulse Ion Counter for continuous 1: 107 c/s decade dynamic range
  • Extended dynamic range  to 5×1010 c/s with Faraday option
  • Enhanced contamination resistance via the RF-only pre-filter stage
  • Signal gating 100 nano second resolution for energy & mass distributions vs time or TOF studies
  • Temperature reading integrated into data displays for thermal desorption applications
  • Integral UHV compatible shroud, Liquid Nitrogen cooled shroud option
  • MASsoft control via RS232, USB or Ethernet LAN
  • Upgradeable to Plasma / SIMS specification




The system is supplied with MASsoft Professional software.

This Windows 8 and Windows 10 compatible software allows control of the instrument via USB 2.0, RS232 or Ethernet. Provides comprehensive I/O for data output and for reading data from external devices for integration and display with mass spectrometer data.
