Abstract

The validity of the choice of the geometric mean wavelength in the differential version of the turbidity spectrum method is analyzed by numerical simulation. It is found that this choice can introduce errors, as large as 5–35%, in the estimated values of parameters of a colloid system. It is proposed to construct the calibrations n=n(α, m) by using the realistic (instrument-dependent) differentiation method, generalized in a way that provides for the monotonic nature of the calibrations.
