Dissolved organic matter
More than 1000 g of Suwannee River natural organic matter (NOM) were isolated using reverse osmosis technology, then H+-saturated, freeze dried, and homogenized. This sample contains only 7 % dissolved organic carbon, representing 92.9 % recovery. The NOM sample is available for 30 USD per 100 mg. The elemental composition of dry Suwannee River NOM is: 52.5 % C; 4.2 % H; 42.7 % O; 1.1 % N; 0.70 % S; 7.0 % Ash. A brief description of the sampling and isolation procedure can be found on the web.
