This poster introduces a new structural probe for colloidal liquids in their neat unperturbed state. The technique combines two recent advances in refractometry – a generalised equation for the refractive index of particulate systems which contains the size and the volume concentration of the dispersed phase and the advent of digital refractometers which measure the refractive index of turbid dispersions with accuracy. Examples of its application include study of fat globules in milk, coagulation of polymer latex and lamellar dispersions.
