Initial Start-up of the Gas Purifier for Removal of
Oxygen and Moisture
Do not open the isolation valves (Figure 3-4) until the inert atmosphere in the
controlled atmosphere glove box main chamber has been reduced below 5000
ppm for both oxygen and moisture. The Gas Purifier arrives fully
regenerated and ready for use. Usually 5000 ppm can be attained through
200 evacuation and fill cycles of inert gas into the glove box. Once 5000
ppm or less is achieved, the Gas Purifier isolation valves may be opened and
the blower turned on. Simply turn the blower ON as identified on the control
panel per Figure 3-7. Once turned ON, the blower circulates inert gas air
from the glove box through the Gas Purifier column; oxygen and moisture
will start to drop immediately. The button switches the Gas Purifier blower
between ON, OFF, and AUTO. ON operates the blower continuously, OFF
shuts the blower down, and AUTO turns the blower on and off if an oxygen
or moisture monitor control range is desired. If AUTO is chosen, the oxygen
or moisture monitor (available from Chapter 7) must be programmed and the
monitor automatically controls the blower function.
The oxygen or moisture monitor should be placed inside the glove box for
best results. The accessory Oxygen/Moisture Monitor Cable (9-pin) and
Electrical 9-pin Sealed Pass-Through must be installed between the monitor
(oxygen or moisture) and the Gas Purifier. Please refer to Figure 3-1, Figure
3-8 and Chapter 7 for accessories and connections for AUTO mode control of
the sealed circulation blower inside the Gas Purifier.
CAUTION: Some chemicals used in a glove box will
“poison” the copper catalyst inside the Gas Purifier and
reduce the oxygen removal capability. These chemicals
should not be used in the glove box in order to avoid
replacing the copper catalyst and molecular sieve.
