Procedure Physicochemical analysis based on the control of interfacial tensions, and corresponding apparatus.

摘要

The invention relates to a process and apparatus for analyzing the behavior of an interface LIQUID / FLUID, PARTICULARLY IN PRESENCE Surfactant. According to the invention IS USED TENSIOMETRO WORKS ON THE PRINCIPLE OF DROP HANGING AND THE AMOUNT OF LIQUID INJECTED INTO THE DROP WITH VALUE OF TENSION INTERFASE CALCULATED syncs: VOLUME BEAD FORMED, INCREASES AS INTERFACE TENSION tends to decrease. SE AS A FORMING PREVEERA GOUT (30) MECHANISM; A MEANS OF ACQUISITION OF A BEAD imgen; Extracting means CONTOUR BEAD (40); Means (50) CALCULATION OF INTERFACE TENSION FROM THE SHAPE AND DIMENSIONS OF CONTOUR; And adjusting means (60). The process uses a measurement method INTERFACE QUICK TENSION USING ALL POINTS OUTLINE DROP AND ALLOWING obtain a value in less than a second with a microcomputer.
