Optical detection of toluene in aqueous solutions by a sensor employing a 4-cm-long sensing region produced by dip-coating a dimethylpolysiloxane layer on the core of a fiber with an inverted-parabolic-index profile was investigated. In 5-min static exposures and 2.5-3-min dynamic exposures detection limits in the low-mg/l range were obtained. Effects associated with the observed cross-sensitivity of the fiber to water and en effect of a change of the solution temperature were also examined.
