Paper Abstract

A completely reversible fiber optic chemical sensor (FOCS) for carbon monoxide (CO) has been recently developed at Physical Optics Corporation (POC). The sensor, consisting of an organometallic complex adsorbed in a short segment of porous optical fiber, demonstrated spectroscopic changes upon exposure to CO. The sensor exhibits a strong absorption peak centered at 435 nm that disappears upon exposure to CO. The absorption peak reappears as the ambient CO partial pressure is reduced. This paper reports the results from testing a FOCS for CO based on the optical transmission at this absorption peak.
