When having to decide which gases need or not need to be pumped with
purge gas we are available to provide assistance.
Refer to Section 4.1 for suited gases.
Consider the additional purge gas flow when selecting a suitable backing
pump.
We recommend a purge gas flow of 0.4 mbar·l/s (24 sccm) with Nitrogen.
The pressure in the pump must not exceed atmospheric pressure.
Observe Safety Information 0.1.2 to 0.1.5.
The purge gas is fed either through an activated valve or a manually operated
throttle.
