Maintenance for the Sample Probe
Thermo Fisher Scientific Omni FTIR Multi Gas CEMS Instruction Manual 5-7
Use the following procedures to perform maintenance on the sample probe.
Maintenance procedures are performed periodically to keep the sample
probe running efficiently.
WARNING Aggressive condensate is possible. Wear protective glasses and
proper protective clothing. ▲
WARNING
High surface temperatures! Wear protective gloves. ▲
WARNING Flush probe in the case of toxic gases. ▲
CAUTION Before turning off power to the probe, i.e. turning off the
heaters, the probe should be flushed with inert gas or air in order to avoid
condensation of aggressive components of the process gas. This can best be
accomplished by performing a probe zero.
▲
Important Note For any sample probe service procedures that are not
covered in this manual, please consult the M&C operator’s manual. See the
“
Other Manuals ” on page 1-10 . ▲
Use the following procedure to periodically check and/or replace the filter
element and graphite seals in the sample probe. The filter and seals are
located inside of the probe box. The graphite gasket lid seal must be
replaced every time the filter housing lid assembly is removed.
Equipment Required:
Ceramic filter element
Graphite lid seal
Graphite filter seals (as required)
CAUTION High surface temperatures present. Allow sufficient time to
cool. ▲
1. Flush the probe with inert gas or air to clear any toxic gases.
