Abstract
The present disclosure relates to a system (1) for determining at least one of the character, composition and reactivity of dissolved organic matter, DOM in water comprising: an ultraviolet, UV light source (2) configured to excite a water under examination (3) with a light beam (2′) having an excitation wavelength in the range of 250-500 nm. Further, the system comprises a first detector device (4) and a second detector device (5), wherein the system (1) further comprises control circuitry (6) configured to predict at least one of the composition, character and reactivity of DOM in the water under examination (3) based on said first and second fluorescence intensity.

A system for determining at least one of character, composition and reactivity of dissolved organic matter, DOM in water comprising:
- an ultraviolet, UV light source configured to excite a water under examination with a light beam having an excitation wavelength in a range of 250-500 nm;
- a first detector device configured to determine a first fluorescence intensity emitted from said water under examination, the first detector device being arranged to measure at a first emitting wavelength being in a range of 375-405 nm;
- a second detector device configured to determine a second fluorescence intensity emitted from said water under examination, the second detector device being arranged to measure at a second emitting wavelength being in a range of 490-580 nm;
- wherein the system further comprises control circuitry configured to:
- predict at least one of the composition, character and reactivity of DOM in the water under examination based on said first and second fluorescence intensity.
A method for determining character, composition or reactivity of dissolved organic matter, DOM in water, the method comprising the steps of:
- exciting a water under examination with an excitation emission having a wavelength in a range of 250-500 nm;
- determining a first fluorescence intensity emitted from said water by a first detector device measuring at a first emitting wavelength being in a range of 375-405 nm;
- determining a second fluorescence intensity emitted from said water by a second detector device measuring at a second emitted wavelength being in a range of 490-580 nm
- predicting at least one of the composition, character, and reactivity of DOM of the water under examination based on said first and second fluorescence intensity.
