ABSTRACT:
A method for the quantitative estimation of the dispersion medium and one or more components forming the disperse phase of an emulsion or suspension or mixture thereof, wherein the mean particle size of the disperse phase is less than a selected absorption wavelength of the dispersion medium and also less than a selected absorption wavelength for each of one or more components of the disperse phase, and the said selected absorption wavelength of the dispersion medium is at a wavelength differing substantially from the or each selected absorption wavelength for the disperse phase component or components and the absorption by the or each disperse phase component is stronger than the absorption by the dispersion medium at the selected absorption wavelength for the or each disperse phase component.
