8.4 Purging the System
Systems equipped with freezers or other components that may be
protected by covers must be open during the purging process.
If the system has been in use prior to purging, ensure that the
freezer(s) is deactivated and is at room temperature before
beginning the process.
The instructions below include information regarding glovebox systems equipped with
analyzers. The analyzers, which are used to monitor the oxygen and moisture levels inside the
glovebox, can be used to determine when the glovebox atmosphere reaches the desired purity
level.
Glovebox systems which are not equipped with analyzers require the gas consumption to be
monitored to determine when the glovebox atmosphere reaches the desired purity level. Refer
to the Gas Consumption chart in Chapter 3 for more information.
