A new, general and objective approach to locating critical points of fluid mixtures is described (see picture). It is new because it exploits the fact that the liquid phase forms preferentially on the surface of the sensor. It is general because it can be used with any type of surface-sensitive sensor, and it is objective because it is based on the numerical output of a sensor rather than the visual image normally used for phase equilibrium studies.
