Mass Spectrometer

The Residual Gas Analyzer (RGA) based on Quadrupole mass spectrometer is used for real time monitoring of gas concentrations. Sampling can be carried out from high vacuum up to atmospheric pressure. 

Tool

Pfeiffer OmniStar GSD 301 O2

Applications

Real time Gas analysis (including temporal gas concentration monitoring)
