Abstract: A chemiluminescent detecting method includes the steps of uniformly irradiating with radiation a stimulable phosphor sheet formed with a stimulable phosphor layer containing a stimulable phosphor which can store an energy of radiation and be stimulated by visible light to emit the energy of radiation in a form of light, thereby storing energy of radiation uniformly therein, selectively labeling a biopolymer with a labeling substance which can produce chemiluminescent light by contact of itself and a chemiluminescent substance, causing the biopolymer labeled with the labeling substance and the chemiluminescent substance to come into contact with each other, and exposing the stimulable phosphor sheet to chemiluminescent light produced by the contact of the biopolymer labeled with the labeling substance and the chemiluminescent substance.

Abstract: An arrangement for measuring radioactivity of an eluate flow with a flow-through detector arrangement, including at least one radioactivity detector, and a valve arrangement by way of which the eluate flow can be redirected through the at least one radioactivity detector where the radioactivity of the eluate is measurable in a stationary manner.
