3.7 Connecting the eluent degasser
The high-pressure pump cannot generate uniform flow if the eluent con-
tains small gas bubbles or dissolved gas. As a result, the baseline cannot
be stabilized correctly. In order to achieve good measurement results, the
eluent has to be degassed before it goes into the high-pressure pump.
The eluent degasser is completely connected. No installation work is
required.
3.8 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.
