Installing an inline filter
Inline filters protect the separation column reliably from potential contami-
nation from the eluent. The small filter pads with 2 µm pore size can be
replaced quickly and easily. They remove particles from the solutions.
An inline filter (6.2821.120) is installed between the purge valve and the
pulsation absorber as protection against particles.

Installing the pulsation absorber
The pulsation absorber is installed between the high-pressure pump and
the injection valve. It protects the separation column from damage caused
by pressure fluctuations, e.g. when the injection valve is switched, and
reduces interfering pulsations during highly sensitive measurements.
