METHOD AND APPARATUS FOR THE MEASUREMENT OF SURFACE TENSION-RELATED CHARACTERISTICS OF LIQUIDS

摘要

The present invention provides a practical, reliable, quick, accurate method and system for determining a surface tension-related characteristic of a liquid-containing composition, wherein the surface tension-related characteristic is determined from bubble point measurements. The approach of the present invention is accurate, because bubble point measurements are consistently sensitive to even small changes in surface tension-related characteristics of a composition. Such an approach is also relatively quick as a bubble point pressure profile can be determined for a sample in seconds, which makes such an approach suitable for on-line use.
