The migration of fluid substance and/or substance contained in the fluid substance is controlled by disposing a separation medium capable of restricting the migration of fluid substance and/or substance contained in the fluid substance in an intervenient space coupling a first space and a second space. Insertion of a connection medium in place of the separation medium enables initiation of the migration to the second space. Thus the migration , of substances can be easily controlled without resort to mechanical means. This method facilitates two-dimensional electrophoretic analysis on chips.
