Requirements on a Differential Refractometer for its Use in Sizing Colloidal Particles
Most colloidal samples have a non-negligible imaginary component of the effective refractive index due to scattering and absorption losses. In this paper we analyze the requirements on a differential refractometer so that it can be used to measure the real part of the effective refractive index increment in colloids for particle size analysis.
