2.3 Flow diagram
Figure 2 Flow diagram with dialysis and Figure 3 Flow diagram with
ultrafiltration show the flow paths for two with the 2.850.2110 perform-
able inline sample preparation technologies. The paths for sequential sup-
pression (MSM (2-9) and MCS (2-10)) are also shown for both
approaches. Liquid containers (eluent bottle, sample vessel, waste con-
tainer, auxiliary solutions container) and guard column are not shown in
the diagram (see Chapter 2.21, page 64). The arrangement of the mod-
ules in the diagram corresponds to the front view of the instrument.
Which pressure screws, connections and couplings are used, is described
in the installation chapters of the individual modules.
Dialysis
This inline sample preparation technology is applied for samples with
strong matrices, e. g. emulsions, samples containing fat and protein, body
fluids or heavily contaminated waste waters. The dialysis effectively
