What substances can kill a sensor?
Electrochemical CiTiceLs CiTiceLs are designed for operation in a wide range of environments and harsh conditions. However it’s important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments, and operation. Formaldehyde is known to temporally inhibit the operation of Nitric Oxide sensors. Other solvents are known to create false high baselines. When using sensors with printed circuit boards (PCBs), decreasing agents should be used before the sensor is fitted. Do not glue directly on or near the CiTiceL as the solvent may cause crazing of the plastic. Catalytic bead CiTipeLs Certain substances are known to have a detrimental effect on catalytic sensors. CiTipeLs are designed to be resistant to these substances – there are CiTipeLs available which offer excellent resistance – however certain substances should be avoided. The detrimental effect can occur through two mechanism: Poisoning Some compounds will decompose on the catal
