摘要
A method and an apparatus for evaluating a segregation at a solid-liquid interface, capable of specifying and measuring quantitatively a segregation substance, that is, a substance which precipitates preferentially on a solid surface from a liquid or remains preferentially in the liquid (or elutes from the solid surface into the liquid), on the contrary. A reception table (2) having a shallow cup-like upper surface is disposed inside a container (1). After a predetermined inert gas is introduced into the container (1), a sample sheet (3) placed on the reception table (2) is downwardly curved by deformation means such as a vacuum suction mechanism. Thereafter, a predetermined solution is dropped onto the sample sheet (3) through a capillary (4) and the dropped solution is evaporated by a mercury lamp (7). After predetermined evaporation is completed, the sample sheet (3) is taken out from the container (1), and is analyzed by an appropriate one of measuring instruments attached to the apparatus. The instrument used depends on a segregation substance.
