If your facility does not have a source
of
clean, dry compressed air
or nitrogen for system purge, we recommend that you consider using
a purge gas generator. The generator cleans and dries the air supplied
by your air compressor and provides it to the spectrometer. (For
facilities without an air compressor, a complete dry-air generating
system is available; see the next section.)
The spectrometer works well with the Whatman® (Balston®) purge
gas generator models shown at the top
of
the following table, which
lists part numbers and specifications. The generator supply voltage and
frequency are not adjustable, so be sure to order the correct items for
your local utility service. The power consumption
of
the generators is
listed earlier in the section called "Power consumption."
