Class Information
Number: 204/450
Name: Chemistry: electrical and wave energy > Processes and products > Electrophoresis or electro-osmosis processes and electrolyte compositions therefor when not provided for elsewhere
Description: Subject matter drawn to (a) processes involving (1) the travel, transport, or relative movement of one or more particles or components in a conducting liquid or fluent material, other than a gas, under a net unidirectional electric stress or (2) the movement of a liquid inside the capillary spaces of a solid (e.g., membrane, etc.) under the influence of an electric field or (b) electrolyte compositions specialized for use in a process under (a) when not provided for elsewhere.
