A simple method of correction for forward Rayleigh scattering in turbidity measurements
Abstract:
A simple method is developed to correct for primary light scattered forward to the detector in turbidity measurements of Rayleigh scatterers. The relative measurement error, Δτ(err)/τ is shown to be independent of turbidity and specific absorbance, unlike the error calculated by use of a more involved model in the literature. In addition, although both methods address the presence of absorbing components in the sample, only the simple method can be used when absorbing components and/or scattering components of any size (Rayleigh, Rayleigh-Gans-Debye, or Mie scatterers) are present in the blank.
