A specialist gas analysis system for fast event transient analysis

The Hiden HPR-20 TMS Transient MS is configured for fast event gas analysis of gases and vapours at pressures near atmosphere. Ideal for fast gas switching experiments the MS features the Hiden QIC quartz-lined 0.9 m sampling interface.

HPR-20 R&D


The inlet, operating at 200 °C, provides response times of less than 150 ms to changes in gas composition with a 5 decade response time in < 200 ms.

The QIC inlet is coupled directly to Hiden’s Pulse Ion Counting (PIC) digital MS which is capable of measurement speeds of up to 500 data points/s over the entire 7 decade dynamic range.


  • 0.9 m fast response QIC capillary – 150 ms response time
  • Open ion source and optimised pumping configuration for fast response
  • Digital PIC detector – 7 decades continuous log scale
  • Detection of low ppm to high % levels in < 200 ms





The system is supplied with MASsoft Professional Edition software.

This Windows 8 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.
