3.9 Installing the high-pressure pump
The intelligent and low-pulsation high-pressure pump pumps the eluent
through the system. It is equipped with a chip where its technical specifi-
cations and "life history" (operating hours, service data, etc.) are saved.
The high-pressure pump consists of:
￭ The pump head, which pumps the eluent through the system.
￭ The purge valve used for bleeding the pump head.

3.10 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.
