Catalytic sensors are susceptible to poisoning by traces of several substances.
This leads to an inhibition which can be permanent or temporary depending on
the contaminant, the concentration of the contaminant, the duration of
exposure to the contaminant.
Poisoning may result from exposure to substances as:
silicones (e.g. waterproofing, adhesives, release agents, special oils and
greases, certain medical products, commercial cleaning agents)
tetraethyl lead (e.g. leaded petrol, particularly aviation petrol ‘Avgas’)
sulfur compounds (sulfur dioxide, hydrogen sulfide)
halogenated compounds (R134a, HFO, etc.)
organo-phosphorus compounds (e.g. herbicides, insecticides, and phosphate
esters in fireproof hydraulic fluids
Oldham Simtronics recommends regular testing of fixed gas detection installations
(read Chapter 5).
