Ammonia Detection by Dye Immobilized Microstructured Optical Fiber

Abstract:

Article Preview

An optical ammonia probe was fabricated based on Microstructured Polymer Optical Fiber (MPOFs) modified by eosin doped silica gel films.The structure of this probe was based on microstructured polymer optical fibers with microholes and these microholes could be used as the substrate of sensing materials and minor reaction pools. The sensing properties of the optical fiber sensor to gaseous ammonia were investigated at room temperature. The sensing probe showed different fluorescence intensity at 576 nm to different concentrations of trace ammonia in carrier gas of nitrogen. The response range was 20-350 ppm, with short response time within 600 ms.
