Colored Dissolved Organic Matter (CDOM)

Monitoring the chromophoric or colored fraction of dissolved organic matter (CDOM) in natural waters can be an extremely useful tool in a variety of marine and freshwater applications. Scientists have developed numerous methods for measuring or estimating DOM concentration for a variety of biological, chemical and physical research and monitoring topics. Fluorescence detection of CDOM is the easiest and fastest means of estimating DOM by taking advantage of CDOM's natural fluorescent property of absorbing UV light and fluorescing blue light. CDOM measurement is also of interest to researchers due to its effect on light in surface waters and as a natural water mass tracer.
