Stand-alone High Pressure Mass Spectrometer for gas composition analysis from 200 bar to 10-8 mtorr

The RGAPro is a residual gas analyzer designed to work with the PCTPro-2000 or any other gas process for real-time compositional analysis of gas sorption and reaction processes. The system uses a 100 to 300 amu quadrupole mass spectrometer with better than 1 amu resolution. Sophisticated software control of scan and data acquisition allows for various scan modes and includes automatic profile identification based on stored profiles from a standard reference library. The RGAPro is a stand-alone instrument which incorporates a hybrid turbomolecular drag pump and a proprietary gas dosing manifold that allows gas sampling over the entire vacuum to 200 bar operating pressure range of the PCTPro-2000 and gas reaction or processing systems.
