Big particles are flushed away
and do not clog the membrane
High flow on the sample side
Low flow on the acceptor side

Strong concentration gradient
No equilibrium concentration
Cellulose acetate membrane
Sample volume 10 mL
Equilibrium concentration
No filtration, no pre concentration
Unique technique, that had significantly improves the field of application for IC
