Key Features
  • 0 to 300 ppb Quinine Sulfate equivalent (QSE) measurement range
  • 0.01 ppb QSE resolution
  • T63<2 sec response time

The EXO fDOM (Fluorescent Dissolved Organic Matter) sensor detects the fluorescent component of DOM (Dissolved Organic Matter) when exposed to near-ultraviolet (UV) light. Users might wish to quantify colored dissolved organic matter (CDOM) in order to determine the amount of light which is absorbed by stained water and thus is not available for photosynthesis. In most cases, fDOM can be used as a surrogate for CDOM.

Questions & Answers
How is this sensor calibrated?
The YSI EXO fDOM sensor is calibrated with quinine sulfate solution. YSI recommends purchasing the necessary reagents from Fisher Scientific - items #6119-70-6 and #AA35651K7; then preparing the solution according to the EXO user manual (section 5.11). As Fondriest Envionmental does not sell these reagents, we recommend contacting YSI directly (www.ysi.com) to ensure the correct standards are purchased.
