Hi Richard,

A list of chemicals that affect performance can be found on the following application note:

You may need to create an experiment on how the readout is affected with the described condition, as offset will be introduced and the amount may be influenced by duration of exposure, and the concentration of chemical/gas.

Best Regards,
Matt
