Claim:
An electrophoresis apparatus comprising: a transport passage having an inlet entrance and an exit outlet; a first separation passage which intersects with the transport passage at a first intersection; the first separation passage having an inlet entrance and an exit outlet; a first concentrator to concentrate a first analyte; the first concentrator being positioned at the first intersection; a second separation passage which intersects with the transport passage at a second intersection; the second separation passage having an inlet entrance and an exit outlet; a second concentrator to concentrate a second analyte; the second concentrator being positioned at the second intersection; an outlet passage; the first separation passage to convey to the outlet passage the first analyte concentrated by the first concentrator from a sample introduced into the transport passage; the second separation passage to convey to the outlet passage the second analyte concentrated by the second concentrator from the sample introduced into the transport passage; and a detector to identify and characterize the first and second analytes when delivered sequentially thereto in the outlet passage.
