Abstract
A method and apparatus are for characterizing colloids by successive measurements of light attenuation or emission of a colloidal mixture at two or more temperatures and at one or more wavelengths. The difference or ratio of the measurements at two or more temperatures provides a measure of the colloidal stability with respect to temperature. The amount of certain organic colloids that are unstable to temperature variation may be determined from the magnitude of the measurement change. In appropriate mixtures, this method provides a means to distinguish components of colloidal substances based. This method may be specifically applied to determining the stability and concentration of colloidal pitch or wood resin in a pulp or paper process water. In this context it may be used to distinguishing colloidal pitch or wood resin from talc, clay, carbon black, or other fillers.
