Class Information
Number: 96/101
Name: Gas separation: apparatus > Chromatography type apparatus
Description: Apparatus comprising a column containing (a) a liquid, known as the "stationary liquid phase," supported by a base of solid material to successively sorb therein the different gases in a plurality of gases or (b) a solid sorbent to successively sorb thereon the different gases in a plurality of gases with or without subsequently successively eluting or displacing the sorbed gases with a gas which is inert with respect to the sorbed gases and sorbent.
