6.4Purge Gas Cylinder Refill

The analyzer uses one of two types of purge gas:

N2 purge gas for H2 measurements

CO2 purge gas for N2 or H2 measurements

You will need a model 32824A refilling hose to refill the purge gas cylinder.

CAUTION:

Only trained personnel should perform this filling operation. These persons should be aware of safety procedures furnished by the storage gas supplier, and any applicable regulations issued by local health and safety authorities.

Always wear safety glasses and gloves when performing any refill operation.

6.4.1 N2 Purge Gas

Fill the N2 purge gas cylinder to a maximum of 200 bar from a master N2 storage cylinder, using fittings supplied with the analyzer.

CAUTION:

Although N2 is not toxic, it is asphyxiating. Therefore, filling should be carried out in a ventilated place and leaks should be avoided.

Note:

Do not attempt to refill the analyzer purge gas cylinder if the master N2 storage cylinder pressure is below 100 bar. When the master cylinder is below this pressure, refill or replace the master cylinder.
