Operating instructions ULTRAMAT 23 gas analyzer
C79000-B5276-C216-03
2.4 Gas Conditioning
The sample gas must be sufficiently conditioned to prevent
contamination of the parts through which it flows. The ULTRAMAT 23
is usually preceded by
S
a gas sampling device with filter,
S
a sample gas cooler,
S
an analysis filter (1-2
μ
m) and
S
an external gas suction pump (with sample gas lines > 20 m)
(see Fig. 2.1).
Notice
With the analyzer version with pipe 1.4571, there is no safety filter and
no condensation trap in the internal gas path. Therefore correct gas
preparation must always be ensured!
Depending on the composition of the sample gas, additional equipment
may be necessary such as e.g. a washbottle, additional filters and a
pressure reducer.
