• The use of a non-bottled gas source is recommended, such as
♦
A nitrogen generator with suitable air compressor or with a
suitable in-house air source
♦
Medical-grade nitrogen from an in-house liquid nitrogen source
TIP Use of smaller compressed nitrogen cylinders or liquid nitrogen
containers may be a quick and easy source of nitrogen during
installation. However, it is not recommended for routine operation.
•
The gas consumption of the detector is typically ≤ 4 L/min.
•
The supply gas must be free from water vapor, free from particles,
and must not contain non-volatile hydrocarbons, such as
compressor oils.
If necessary, use a sub-micron particle filter or carbon filter in
combination with a water condensation trap located close to the gas
source.
• Make sure that the gas supply is ready for operation. Follow the
instructions in the User Documentation for the gas supply.
