摘要
In a method of determining spinodals, and particularly critical points, associated with phase transitions in samples of chemical solutions, a sample is subjected to relatively fast thermal pulses, and measurements of a physical variable of the solution are concurrently made. The physical variable may be any property, such as light-scattering intensity, the value of which property varies strongly around the spinodal or critical point. The thermal pulses may, for example, be applied to the sample by means of two fluid baths controlled at different temperatures, the temperature of one bath being changed slowly. Fluid is passed from the two baths, alternately, into heat-exchange relationship with the sample. In an alternative apparatus, a single fluid bath may be used, the fluid being passed into heat-exchange relationship with the sample either without further heating or with further heating by a heater adjacent to the sample.
