Patent ID: 6929943

Claim:
A device for analyzing sandwich immunoassays with a liquid assay medium, comprising: a plurality of vessels for holding the assay medium, each of the vessels having a base comprised of a solid body, the solid body having a first side wall and a top surface constituting a bottom surface of the vessel and forming a boundary surface of the solid body, wherein first reaction agents are dissolved in the assay medium in the vessel and are labeled with a luminophore or different luminophores and second reaction agents are bonded to the boundary surface within a boundary layer of the assay medium; a plurality of transmitters for emitting light rays that are coupled into the base of each vessel via the first side wall and conducted at a total reflection angle to the boundary surface so that luminophore-labeled first reaction agents that are bonded to the second reaction agents are optically excited by at least some of the light rays and emit at least one of fluorescent and phosphorescent rays; a polygonal mirror; and a receiver positioned for quantitatively detecting the at least one of the fluorescent rays and phosphorescent rays, wherein the plurality of transmitters are activated individually, one after another, and the plurality of vessels are arranged concentrically to the polygonal mirror so that the fluorescent rays exiting at the vessels are conducted via the polygonal mirror to the receiver, and the receiver is a common receiver for recording the fluorescent rays exiting from the individual vessels.
