Document Type and Number:

WIPO Patent Application WO/2006/085604

Kind Code:

A1

Abstract:

This invention provides a method for automating a procedure comprising carrying out electrophoretic separation of a sample liquid as an analyte and then separating and removing a lid part bonded and fixed on the upper surface of a substrate part constituting a lidded “microchip”. This method comprises carrying out desired electrophoretic separation of a liquid sample of an analyte utilizing a flow passage provided in a lidded microchip, and then freezing a water solvent contained in the liquid sample, which has been subjected to the electrophoretic separation, held within the flow passage, lifting the end of a lid part hermetically sealing the upper surface of a grooved flow passage provided on a substrate part at a predetermined speed while maintaining the whole sample subjected to the electrophoretic separation in the frozen state, and separating and removing the lid part from the substrate part under such conditions that maintain flexure having a predetermined radius of curvature.
