Abstract

The manuscript is a review of basic essentials to ozone gas sensing with optical methods. Optical methods are employed to monitor optical absorption, emission, reflectance and scattering of gas samples at specific wavelengths of light spectrum. In the light of their importance in numerous disciplines in analytical sciences, necessary integral information that serves both as a basis and reference material for intending researchers and others in the field is inevitable. This review provides insight into necessary essentials to gas sensing with optical fibre sensors. Ozone gas is chosen as a reference gas. Simulation results for ozone gas absorption cross section in the ultraviolet (UV) region of the spectrum using spectralcalc.com simulation have also been included.

Abstract

Laboratory design of an ozoneconcentration regulator which is build on the theory of continuity equation forgas flow in parallel pipes in conjunction with the ozone elimination potentialsof an ozone destructor is presented. At an initial oxygen flow rate of 33.33 cm3s-1,ozone concentration was  generated andvaried between 429.30 parts per million (ppm) to 3826.60 ppm.  Similarly at an initial oxygen flow rate of 25cm3s-1, ozone concentration was  generated and varied between 387.30 ppm to4435.20 ppm. Effect of flow meter when the ozone concentration was set toapproximate 1000 ppm  were investigatedand reported. Fine tuning of the regulator is necessary to ensureconcentration stability for long duration experimental work. DOI: http://dx.doi.org/10.11591/telkomnika.v13i2.6952
