Title:
ELECTROPHORETIC SEPARATION CHIP
Document Type and Number:
WIPO Patent Application WO2003106986
Kind Code:
A3
Abstract:
A method for collecting an analyte species from a sample is provided, the method of collection potentially being supplemented to give a method of preparing a sample for analysis and / or a method of analysis. The method including providing part of a sample in a substrate, causing the sample to migrate to an interface between the substrate and a second substrate due to the action of an electrical potential difference, the electrophoretic velocity of the analyte species of the second substrate being balanced by or exceeded by the bulk flow velocity of the second substrate and the bulk flow velocity of the second substrate being in an opposing direction to the electrophoretic velocity of the analyte species in the second substrate. In this way substantial concentration of the analyte species at the interface is provided. Subsequently the species can be conveyed away from the interface for further preparation and / or analysis.
