Abstract

A carbon monoxide fiber optic probe has been developed with a porous polymer optical fiber. The carbon monoxide sensing reagent is palladious chloride which was dissolved in the monomer solution before forming the porous polymer fiber. Other than the high sensitivity, the porous polymer fiber, made by heterogeneous crosslinking polymerization, exhibits very high gas permeability and liquid impermeability. The trapped indicator is very stable to atmosphere and enables this optical fiber probe to be used as a "chemfuse" for a carbon monoxide warning system. The porous sensing segment can be attached to regular waveguides by fiber optic couplings, therefore, it can be easily replaced. A linear response of this probe was observed for 1% to 100% of carbon monoxide in air. The temperature effect and interference from other gases with this probe have been investigated.
