Abstract

We examine concentration of solution with the help of a set-up with two experimental fiber optic sensors, utilizing intensity modulation by reflection as well as evanescent wave absorption. The output by evanescent field sensor shows good sensitivity along with change in concentration as compared to the reflection based sensor. It has been observed that former set-up provides a significant marginality of 0.0275 V/g ml over the latter with utilization of same analyte with good degree of repeatability.
