3.10 High pressure pump
The intelligent and low pulsation high pressure pump pumps the eluent
through the system. It is equipped with a chip on which its technical spec-
ifications and "life history" (operating hours, service data, ... ) are saved.
The purge valve is used for deaerating (see Chapter 3.10.2, page 45)
the high pressure pump.
