Abstract

This paper describes an optical fiber sensor for the monitoring of ammonia gas. An open path optical technique is used to analyze the absorption lines of ammonia within the Ultra Violet region. The optical fibre sensor shows absorption lines comparable to the theoretical ammonia spectra. Cross sensitivity with carbon dioxide and oxygen gas has also been tested and clearly shows that these two gases have no effect on ammonia measurement in the ultra-violet region, between 200 nm and 230 nm.
