Do I still need RGA Windows?
i
PPM100 is not a complete substitute for RGA Windows.
RGA Windows offers several RGA data display options that are not feasible in a standalone,
monochrome display unit as the PPM110. Obvious examples include: bigger screen, color-coded gas
traces, fast display update, scan logging, deeper data buffers and hard disk data storage.
RGA Windows is still sometimes required to perform RGA tuning operations such as: (1) mass axis
calibration, (2) sensitivity calibration, and (3) E. MULT. gain adjustment. However, RGA users must
keep in mind that these procedures are rarely required during routine vacuum measurements.
i
PPM100 is not recommended for very fast data acquisition applications
RGA users interested in fast data acquisition rates (i.e. such as fast-TPD, or laser desorption experiments)
must still rely in the faster PC/RGA Windows setup for data acquisition. Consult the factory for specific
details.
