The Edwards RGAs are quadrupole mass spectrometers with a high-performance analyzer tube consisting of the ion source, the quadrupole filter, and the detector. We offer two variants, giving you the perfect choice for your various needs.

PRA: Our Primary Residual Gas Analyzer is the perfect solution for all “basic” applications and processes, to do quick and convenient analysis.

WRA: Our Wide Range Residual Gas Analyzer, for advanced and more demanding processes and analysis allowing higher analyzer temperatures and bake out temperatures of up to 300°C.

To match advanced needs, the WRA offers a better sensitivity to detect even the smallest traces of molecules.
