If the high-pressure pump is used to pump a low-pressure gradient, then
the input for the high-pressure pump has to be connected to the low-
pressure gradient module. Follow the instructions in chapter Installing the
low-pressure gradient, page 43.
3.10 Installing an inline filter
Inline filters reliably protect the separation column from potential contami-
nation from the eluent. The small filter plates with 2 µm pore size can be

An inline filter (6.2821.120) is installed between the purge valve and the
pulsation absorber as protection against particles.
