    • A non-invasive radio nuclide detection meter is disclosed which allows accurate counting of radio nuclide substances. The present invention has a control unit coupled to a sample holder. The sample is held in a shielded container and a phosphor scintillation detector is used to detect low energy photon emission or Bremsstrahlung. The low energy photon emissions are measured by energy readings through a six channel counter which counts emissions from at different energy levels. By measuring scintillation energies from the phosphor and counting the photon emissions at different energy levels from the ratio nuclide sample, amounts of impurities may be estimated and the activity determination of the sample may be corrected.

    • A fluorescence analysis system detects light transmitted from wells in a sample plate. One embodiment of the system includes a single light detector. A reflector is capable of receiving light from any one of several detection emitters and of reflecting the light toward the light detector. One reflector includes a prism which is mounted on a stepping motor. The prism is selectively rotated so that it faces each detection emitter in turn. The light from several wells in a row is directed toward the light emitter by rotating the prism to face, one-by-one, each of the emitters corresponding to the wells. The detection emitters include one end of an optical fiber bundle. The other end of each bundle is positioned near the wells, with each bundle positioned by a different well to carry light from that well to the corresponding emitter. A collimating lens is positioned between each detection emitter and the rotating prism to focus light from the emitter onto the prism. A baffle is positioned between the light detector and the prism. Light from a xenon arc excitation lamp is carried by optical fiber bundles toward the sample wells. A computerized controller coordinates light detection with the activities of an automated liquid handling system.
