The Dycor Benchtop Mass Spectrometer is a compact versatile gas analysis system for sampling gases over a wide range of pressures, from high vacuum up to and beyond atmospheric pressure. The analyzer and inlet system can be removed from the frame and placed up to 10 feet from the pumping station using the included cable and vacuum hose.

This system includes a Dymaxion RGA with enclosed ion source, capillary inlet manifold, compound turbomolecular pump, dry pump, pump controller and laptop PC running Dycor System 2000 software. Systems can be designed for your specific applications.
