DEFINITION

Classification: 530/417

Chromatography or by septum selective as to material, e.g., gel filtration, molecular sieve dialysis, etc.:

(under subclass 415) Processes in which a protein is separated from a liquid mixture by a solid sorbent which competes in affinity with a moving carrier liquid or solvent such that a separation is effected by differing speeds of travel through the solid sorbent.

(1) Note. See Class 210, subclass 658 and the notes thereunder for disposition of chromatography in that and related classes, and Class 210, subclass 635 which provides for gel chromatography.

(2) Note. This subclass provides for high performance liquid chromatography.
