Alternative wavelength for linearity preservation of Beer–Lambert Law in ozone concentration measurement

Abstract

ABSTRACTBeer–Lambert law deviation is often observed. Here, we propose alternative wavelength 279.95 nm for ozone concentration measurement between 357 and 971 μL L−1 to preserve linearity. Sensor loses linearity below transmittance 0.2165, as sensor approaches saturation. We recommend measurement of ozone concentration above transmittance of 0.2165 for strong linear relation. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1013–1016, 2015
