Class Information
Number: 210/635
Name: Liquid purification or separation > Processes > Liquid/liquid solvent or colloidal extraction or diffusing or passing through septum selective as to material of a component of liquid; such diffusing or passing being effected by other than only an ion exchange or sorption process > Liquid/liquid or gel type (i.e., jellylike) chromatography
Description: Process in which the extracting liquid is relatively immobile and an equilibrium of the dissolution or suspension of a constituent between the two liquids is set up such that the constituent moves through the extracting liquid at a slower rate than the movement of the treated liquid and said constituent tends to concentrate in a specific volume of the extracting liquid.
