METHOD AND EQUIPMENT FOR DETERMINING THE STABILITY OF AN EMULSION

摘要

A method and equipment for determining the stability of an emulsion placed in an analyser cell and produced by mixing two non-miscible primary phases (6, 7), namely a conductive continuous phase and a non-conductive dispersed phase. The method comprises a step of measuring changes in conductivity within said emulsion in a portion of the cell which corresponds to the space occupied by one of said primary phases (6, 7) (either the conductive phase or the non-conductive phase) when they are at rest. The equipment for carrying out the method consists of an analyser cell (1) provided with conductivity measurement electrodes (3) connected to a conductivity meter. The electrodes (3) extend vertically through a portion of the cell column (1) and measure the conductivity of the sample being analysed therein, which portion corresponds to the space occupied by one of said primary phases (6, 7).
