5.2 Gas Conditioning (Sample Handling)
To ensure trouble-free analyzer operation one has to attach great importance to gas conditioning:
All gases must be conditioned before supplying!
When supplying corrosive gases ensure that gas path components are not
affected!!
Flammable gases must not supplied without additional protective measures!
It is prohibited to supply explosive gases!
Furthermore the gases must be
❏ dry
❏ free of dust
❏ free of aggressive components affecting gas path materials (e.g. by corrosion).
If moisture can not be avoided take care that the gas‘ dew point is at least 10 °C below ambient
temperature to avoid condensation within the gas path.
Pressure and flow have to be within the limits given in the technical data section.
For suppressed ranges a constant pressure (+- 1 psig at 20 - 25 psig) and constant temperature
(20 - 30 °C, 68 - 86 °F) are very important.
Suitable gas conditionning hardware may be supplied or recommended for specific analytical
problems and operating conditions.
