LUM-100 Luminometer

Introduction to Luminescence...

Certain kinds of chemical or biological reactions produce light as a byproduct of the reaction. This light emitting process is known as luminescence. Examples of luminescence include the light from fireflies as well as the light that is emitted by certain deep-sea life forms.
   The chemiluminescence or bioluminescence reaction can be artificially induced in order to measure the quantity of a particular chemical or biological material in a sample. Any one of four techniques that convert the emitted light into electronic signal can measure the light emitted from a luminescence reaction. These four techniques include  a photomultiplier tube (PMT), an avalanche photo diode (APD), a charge-coupled device (CCD), and a CMOS device. Of these four techniques, the photomultiplier tube offers the greatest detection sensitivity.
     Luminometers measure the count value of the detected light as relative light intensity (RLU). Since the RLU varies from instrument to instrument for the same sample measurement, each system must be calibrated by the user.
