The perfect balance of high end performance and accessibility Description of the technology The Edwards RGAs are quadrupole mass spectrometers with a high performance analyser tube consisting of the ion source, the quadrupole filter and the detector. Exposed to vacuum, the gas molecules are ionized by the RGA. Dependent on the weight or mass of the molecules, the ions have a different mass to charge ratio. By varying the voltage the RGA can measure the different masses: Only ions with the specific mass to charge ratio find their way into the detector where the ionized gas molecules are then measured....

Choosing the right RGA We offer two variants, giving you the perfect choice for your various needs. PRA: Our Primary Residual Gas Analyser is the perfect solution for all “basic” applications and processes, to do quick and convenient analysis. WRA: Our Wide Range Residual Gas Analyser, 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. The Edwards RGAs offer the unique feature of integrated display and...
