At very high levels (i.e. % levels), highly oxidising gases (e.g. ozone, chlorine) will interfere to the extent of their oxygen equivalent, but most other commonly occurring gases will have no effect. ACID GASES Acid gases such as CO2 and SO2 will be absorbed by the electrolyte and tend to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of approximately 0.3% of signal per 1% CO . SGX-VOX sensor is not suitable for continuous operation in concentrations of CO 2 2 above 25%. The SGX-VOX sensor is not designed for use in applications where anaesthetic gases are present.
