Development of a portable laser-induced fluorescence system used for in situ measurements of dissolved organic matter
A portable laser-induced fluorescence system (total weight about 1.7 kg) has been developed for detecting the level of dissolved organic matter in water. The portable system consists of a high pulse repetition frequency (10-kHz) microchip laser at 405 nm, a reflective fluorescent probe and a broadband micro spectrometer. The stability and sensitivity of the new instrument were studied. The dete...
متن کاملMolecular characterization of dissolved organic matter (DOM): a critical review.
Advances in water chemistry in the last decade have improved our knowledge about the genesis, composition, and structure of dissolved organic matter, and its effect on the environment. Improvements in analytical technology, for example Fourier-transform ion cyclotron (FT-ICR) mass spectrometry (MS), homo and hetero-correlated multidimensional nuclear magnetic resonance (NMR) spectroscopy, and e...
متن کاملFluorescence Spectroscopy as a Potential Tool for In-Situ Monitoring of Dissolved Organic Matter in Surface Water Systems
Water is a common substance, yet life cannot exist without it, being the major component of all living things. Considering the tremendous impact water has on life health, it is always an imperative task to study its quality. During the past decades, more advanced techniques were developed not only to generally characterise the water quality, but also to analyse DOM fractions. Organic matter is ...
متن کاملSource characterization of dissolved organic matter in a subtropical mangrove-dominated estuary by fluorescence analysis
Measurements of dissolved organic carbon (DOC), UV–visible, fixed wavelength fluorescence, and synchronous fluorescence were performed in an effort to characterize spatial and temporal variability in concentration and source of dissolved organic matter (DOM) in surface waters of the southwest coast of Florida. Concentrations of DOC in the surface water ranged from 318 to 2043 AM and decreased f...
متن کاملUsing Dissolved Organic Matter Fluorescence to Signal Changes in Carbon Cycling During a Cave Stream Experiment
Cover Photo: Cave salamanders (Eurycea lucifuga) are often found in the "twilight zone " area. This zone is near the entrance of the cave where a small amount of natural light still falls. E. lucifuga feed mainly on various insects and spiders. In the fall one might find their eggs in little crevices of rocks that have water/moisture in them or along rimstone pools. This particular specimen was...
