Sputter Process Monitor SPM 220

Real time sputter process gas analyses to 10-2 hPa

The Sputter Process Monitor SPM 220 provides the perfect solution for qualitative and quantitative gas analyses of sputter processes. The combination of the HiPace turbopumping station and mass spectrometer system with a specially developed SPM ion source enables precise up-to-the-minute process gas analysis up to a pressure of 10-2 hPa.

As an option, Pfeiffer Vacuum also offers a version with a differentially pumped orifice flange, which makes direct process gas analyses of up to a pressure of 10 hPa possible.
