Presentation - National Water Research Institute

To examine production as a function
of CDOM size, water samples were
size fractionated by tangential flow
ultrafiltration on custom built Soluble
Organic Concentrator (SOC;
Separation Engineering Inc.,
Escondido Ca) with a 1000 Dalton
polyethersulfone membrane.
› Concentrate made back up to original
volume with artificial seawater adjusted
to sample’s initial salinity to minimize
potential dilution and solution medium
effects.
