The Hiden ExQ quantitative gas analyzer is a mass spectrometer system providing continuous on-line analysis of dynamic gas streams at pressures from sub-atmospheric up to 30 bar. The system has a range of process interface options that enable adaptation of the system for direct connection to the majority of standard thermogravimetric analysis and thermal analysis instruments.

The system monitors gaseous species through the mass range to 300 amu. Minor species composition is measurable down to 100 part-per-billion. External process data, sample temperature, or sample mass change can be imported for combined integration and presentation with the mass spectral data. An optional carbon monoxide analyzer monitors low levels of carbon monoxide. 

The inlet system operates at up to 200 °C with response times less than 300 milliseconds. The fully integrated system is configurable both for benchtop and for rack-mounting operation and is mountable as standard up to 2m from the sampling point.
