Abstract

PURPOSE:To measure a surface active agent in high accuracy and in a short time deciding the end point easily, by using a porous membrane being capable of extracting, an organic solvent phase only, from an emulsion system with a constant condition. CONSTITUTION:A liquid to be titrated 4 is put in a receptacle for a liquid to be titrated 1 and a stirring blade 3 is rotated by a magnetic stirrer 2 and also, an organic solvent phase extraction part 10 is immersed in the liquid 4 and then, only the organic solvent phase is separated continuously passing said phase through a porous thin film 13 by a microtube pump 7. Separated phase is introduced into a spectrophotometer 5 and the absorbance of the organic solvent phase is measured. On this occasion, a titration burette 20 is controlled by a titration control device 21 recording the titration curve. A porous thin film made of fluororesin such as polyfluoroethylene resin, polyfluoropropylene resin is suitable and its pore diameter is 10-100mu.
