Poisoning
CiTiceLs are designed for operation in a wide range of environments and harsh conditions. However, it is
important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into
instruments, and operation.
When using sensors with printed circuit boards (PCBs), degreasing 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.
Cross Sensitivity Table
Whilst CiTiceLs are designed to be highly specific to the gas they are intended to measure, they will still respond
to some degree to various other gases. The table below is not exclusive and other gases not included in the table
may still cause a sensor to react
