Tangential-flow ultrafiltration, marine

Benner, R., B. Biddanda, B. Black, and M. McCarthy. 1997. Abundance, distribution, and stable carbon and nitrogen isotopic compositions of marine organic matter isolated by tangential-flow ultrafiltration. Marine Chemistry 57 243—263. [Pg.135]

To aid in the characterization of the DOM pool, marine organic chemists have developed techniques fiar separating compounds into size fractions. Tangential flow ultrafiltration is used to isolate a high-molecular-weight (HMW) fraction from a low-molecular-weight (LMW) fraction. The size cutoff between these is approximately 1 tun, which equates... [Pg.611]

Recent innovations in filtration technology include tangential flow ultrafiltration methods that act as preconcentration methods for studies of marine biopolymers such as proteins (see also the section on Adsorption techniques below). [Pg.5023]
