| Abstract: | Gas cells of different length have been previously designed for measurement of ozone through ultraviolet absorption spectroscopy, but each gas cell is used for measurement of single range of concentration only. In current work, practical ranges of ozone concentration measurement for transmissive gas cells between 0.05 m and 0.50 m are theoretically calculated and verified via SpectralCalc.com gas cell simulator. Selections of optical path length and concentration range to be considered practical are justified. Gas cell of optical path length 0.05 m is found to be practical for measurement between 3.57 ppm and 471.61 ppm. Decrease of range of concentration measurement is observed when optical path length is increased from 0.05 m to 0.25 m. However, further increase of optical path length beyond 0.25 m has small effect on reduction of dynamic range of concentration |
