Fluorescence Spectroscopy



The light level from fluorescence is often at the photon counting level, requiring a photomultiplier module for light detection. Measurement of time resolution to the sub-nanosecond level is also important

Photomultiplier modules are used as detectors in chromatography applications where fluorescence methods are used.
