Description
A variety of light sources are available for fluorometry and spectrophotometry. These include deuterium, mercury and xenon arc lamps and quartz halogen bulbs dependent upon the wavelengths required. However, the advent of light emitting diodes has greatly increased the possibilities for the application of fluorometry and spectrophotometry to areas that were previously not practicable, and at a much reduced cost.
