HPR-20 EPIC

With electron impact / electron attachment ionization modes

The Hiden HPR-20 EPIC gas analysis system is configured for continuous analysis of gases and vapours at pressures near atmosphere in standard form, alternative inlet systems being offered for applications requiring direct sampling from higher pressures to 30 bar.

The Hiden QIC quartz-lined sampling interface operating at up to 200oC provides fast response times of less than 300 milliseconds for most common gases and vapours, including water vapour.

The system includes the Hiden EPIC triple filter mass spectrometer including a high gain pulse ion counting electron multiplier detector with positive and negative ion detection. Analysis is both by standard electron impact ionization and by appearance potential soft ionisation (APSI-MS).

The system includes a software selectable mode, electron attachment mass spectrometry (EA-MS), to analyse negative ions formed within the internal ioniser by electron attachment. The electron attachment mode provides vital information for investigating electronegative species, identifying the parent molecules of stable radicals from plasma processes for example.

FEATURES

  • DMM-dynamic multi-mode scanning- uniquely applied for the electron attachment ionization technique for electronegative gas studies
  • Extended mass range options to 1000 amu
  • Pulse ion counting electron multiplier detector with 7 decades continuous dynamic range
  • QIC inlet providing <300 ms response time to changes in gas concentrations
  • Fast scan speeds, with up to 650 measurements per second for transient analysis

SOFTWARE

The system is supplied with MASsoft Professional Edition 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.
