
Flow rate of the zero air: If the previous two variables are constant, the permeation rate of
air into the zero air stream will be constant. Therefore, a lower flow rate of zero air produces
higher concentrations of SO
permeation rate; hence, variations in concentration can be achieved by changing the IZS
temperature.

The IZS option includes an external zero air scrubber assembly that removes all SO
from the zero air source. The scrubber is filled with activated charcoal.
