An apparatus for reading flat, substantially planar two-dimensional gel electrophoretograms containing ..beta..-ray-emitting labeled compounds, the apparatus comprising in combination: a. a single, substantially flat and rectangular proportional chamber radiation detection means substantially parallel to and approximately coextensive with the gel electrophoretogram for receiving ..beta..-rays emitted from the electrophoretogram and cosmic rays and generating electrical signals according to the two dimensional coordinates of each ..beta..-ray and cosmic ray received thereby; b. substantially flat and rectangular scintillator means located nearby to the substantially flat and rectangular proportional chamber radiation detection means for detecting the incidence of cosmic rays on the substantially flat and rectangular proportional chamber radiation detection means and having an electrical output in response thereto, yet having substantially no sensitivity to the ..beta..-rays emitted from the gel; c. magnetic field generating means for providing a substantially uniform magnetic field having dimensions substantially coextensive with the rectangular dimension of the substantially flat and rectangular proportional chamber radiation detection means and passing substantially perpendicularly therethrough and through the scintillator means.
