Abstract

Photon emission of biologically active samples by injection of bioluminescent enzymes are detected by photomultiplier tubes in a luminometer instrument. These photomultiplier tubes are very sensitive to small amount of light and this sensitivity depends, among other factors, on the high voltage applied to the tubes.

This thesis describes a new procedure to automatically calibrate the photomultiplier tubes in the above instrument, discusses the instrument’s design, its implementation, and presents the tests’ results obtained with the actual instrument.
