DISPOSITIVO PARA EL CONTROL DE UNA SOLUCION DE LAVADO QUE CONTIENE SUSTANCIAS TENSIOACTIVAS

摘要

The apparatus comprises a source of linearly polarized light to be propagated through the washing solution and to be diffuced by the micelles and the emulsion. Photodiodes receive the diffused light through respective analyzers oriented with their polarization directions parallel to the polarization direction of the primary light, and perpendicularly thereto, respectively. The apparatus determines the condition of the washing solution at the microscopic level by the use of variations of the polarization of the radiation diffused by the micelles and by the emulsion.
