￭ Remove the 6.2744.040 coupling between the column inlet capil-
lary and the eluent inlet capillary of the MSM-HC.
￭ Connect guard column (optional) (see Chapter 3.21, page 67)
– Fasten the guard column to the end of the column inlet
capillary according to the specifications contained in the
leaflet accompanying the guard column.
– Rinse guard column.
￭ Connect the separation column (see Chapter 3.22, page 69)
– Fasten the inlet of the separation column either to the end
of the column inlet capillary or to the guard column (if
used) according to the specifications contained in the leaf-
let accompanying the column.
– Fasten the MSM-HC capillary labeled with Eluent with a

3.3 Installation diagram
Figure 3 Installation diagram shows the capillary connections with the
application of the gradient technique and sequential suppression
(MSM-HC and MCS).
The arrangement of the modules in the diagram corresponds to the front
view of the instrument. Liquid containers (eluent bottle, sample vessel,
waste container, auxiliary solutions container) and guard column (see
Chapter 3.21, page 67) are not shown in the diagram.
Most of the capillaries are already pre-installed at the time the instrument
is delivered. Capillaries on which nothing needs to be done at the time of
initial installation are not numbered in the diagram.
