8 Rinsing line with return valve
In the diffusion module (6), a segment of the transport buffer is enriched with
the analyte from the donor stream. After time-dependent enrichment in the
diffusion module(6), the acceptor stream flows into the conductivity cell(4)
for assaying the analyte. The conductivity cell is fixated by a retaining plate,
which can be fastened or loosened with a knurled nut(5). Furthermore, a
rinsing line with return valve(8) is attached to the conductivity cell. Before
the solutions are transported to waste, they each run through a drip count(7).
