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.

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.
The inline filter is completely connected. No installation work is required.
