METHOD AND APPARATUS FOR CONCENTRATING A SOLUTE IN SOLUTION WITH A SOLVENT

摘要

A method and an apparatus for forming a prescribed concentration of a substance in a mixture with a fluid from a dilute mixture which is a solutio n of a solute in a solvent, the apparatus (10) including a frame (12) carrying a vertically oriented syringe (14), a stepper motor (16), a laser micrometer (18), a heater (38) for heating and evaporating a drop of the solution suspended from the syringe to concentrate the solution, and further for heating the concentrated solution after it has been loaded into a source, evaporating the solvent and plating the solute onto the surface, and a contr ol system.
