3.2 Oxygen Measurement
3.2.1.1 Cross Interferences by Accompanying Gases
The table below shows, how accompanying
gases interfere the paramagnetical oxygen
measurement. If the concentration of such
gases is already given at time of enquiry, this
interference may be taken into account during
factory startup and thus minimized (option).
