Gas Connections - RMG PGC 9300 Operating Manual

Note
Some parameters for specifications have to be adjusted after switching
the analytical computer on for the first time.
These values must be checked and changed as necessary (refer to the
manual for the analytical computer GC 9300)!
The changed values are saved and then remain available after the com-
puter has been shut down.

4.2 Gas connections

The supply lines for connections A - M (Figure 5: Separation of Ex zones) are de-
signed as 1/8" pipelines with a compression fitting connection. Appropriate particle
filters are arranged upstream from the analytical device. The lines should be stain-
less steel and free from soiling, grease, solvents, etc.
Note
In order to prevent contamination with dirt or environmental air, the sup-
ply lines must be gas-tight in the relevant pressure range.
If it is necessary to seal threads or screw connections, only use Teflon
tape for this purpose.
(Of course, this does not apply for compression fittings!)
Avoid using liquid leak detecting agents.
The tightness of all connections is extremely important for a proper analy-
sis.
The gases must be connected to the process gas chromatograph in compliance
with the rules for working with pure gases (VDI 3490 page 3, Dec. 1980).
Note
It must be ensured prior to commissioning that the gases that are used
correspond to the specified requirements.
