<p>A device and method for the detection of light emitted by chemically reactive substances is disclosed. The device comprises a plurality of wells (21a) for holding chemically reactive substances, a detector (80) for detecting light emitted by the chemically reactive substances held in each well, and moving component for moving the detector sequentially to each respective one of a series of detection positions, proximate to each well, so as to enable the detector to detect the light emitted by the chemically reactive substance in each well. The detector employed in the present invention comprises a photomultiplier tube (80) and, in accordance with the invention, a processor (50) is employed to control the gain of the photomultiplier tube.</p> |
