24 ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A
Sample gas inlet conditions
The analyzer system may not be used for the measurement of ignitable
gas/air or gas/oxygen mixtures during normal service.
CAUTION! The analyzer system may not be used for the measurement of gases con-
taining organometallic compounds, e.g. lead-containing fuel additives or
silicone oils.
If the analyzer system is used to measure HF, all seals in contact with the
sample gas must be made of FFKM. This applies also and particularly in the
case of a gas sampling probe with filter and a sample gas line delivered sep-
arately.
NOTICE The seals in the analyzer system that come into contact with the sample gas
generally consist of FFKM.
