4.3 Gas Conditioning
In order to ensure trouble-free operation, spe-
cial attention must be paid to the preparation
of the gases:
All gases must be conditioned
before supplying to the analy-
zer, to be
• dry,
• free of dust and
• free of any aggressive com-
ponents which may damage
the gas lines (e.g. by corro-
sion or solvents) .
Flammable gases must not be
supplied without additional
protective measures.
Purging option
The purging medium (e.g. to minimize CO
2
interference or for enhanced safety when
measuring corrosive or poisonous gases)
must be dry, clean and free of corrosives
or components containing solvents.
To minimize cross interferences the purge
gas also has to be free of components to
be measured.
Its temperature must correspond to the am-
bient temperature of the analyzer, but be at
least within the range 20–35 °C (68–95 °F).
For information about values for pressure and
ow, please contact your nearest EMERSON
Process Management sales ofce.
If moisture cannot be avoided, it is necessary
to ensure that the dew point of the gases is at
least 10 °C (18 °F) below the ambient tempe-
rature to avoid condensate in the gas lines.
The X-STREAM eld housings can optionally
be tted with heated piping to enable the use
of gases with a maximum dew point of 25 °C
(77 °F).
Pressure and gas ow must remain within
the values given in the
„Measurement
Specication“ section within this manual.
