2.4 Mode of operation for dialysis

Figure 4 Stopped-flow dialysis

Sample is delivered continuously on the sample side of the dialysis cell.

After a rinsing phase, the acceptor flow is stopped. Because of the con-

centration gradient, the ions pass through the membrane. The acceptor

flow remains stationary until a concentration equilibrium is achieved

between the two cell halves. The concentration in the acceptor solution

thus matches the concentration of the original sample. Afterwards, the

acceptor solution is injected directly into the ion chromatograph.
