Abstract
Nonlinear correlation between attenuation and absorption due to the presence of scattering is the main reason for inaccurate spectroscopic quantitative investigations. The polarization subtraction methods are applied to reduce the scattering in order to linearise attenuation to absorption. Monte Carlo simulation shows that the polarized light offers better performance than unpolarized light at giving the most accurate estimate of the concentration ratio of absorbers using the modified Lambert-Beer law. Our results demonstrate that spectrophotometry with polarized technique offers the potential to be a simple and costeffective system.
