18.15 Cleaning the Analyzer
The “Plug in and measure” ISA sidestream gas analyzer should be cleaned regularly. Use ethanol
or isopropyl alcohol with a maximum concentration of 70% and a wet rag to clean the analyzer..
In order to prevent the cleaning liquid and dust from entering into the ISA gas analyzer from the
LEGI interface, the Nomoline sampling tube should be connected all the time during analyzer
cleaning.
Before cleaning the IRMA probe, take off the disposable IRMA airway adapter.
Warning
z The Nomoline sampling tube is not a germ free device. In order to prevent the
sampling tube from causing damages, please never carry out high pressure
sterilization on any part of the sampling tube.
z Never sterilize the ISA sidestream gas analyzer and the IRMA probe or soak them
into a liquid.
z The IRMA oxygen sensor and the IRMA airway adapter are not germ free devices.
Never carry out high pressure sterilization on the equipment; otherwise it will
result in equipment damage.
