Eluent degasser
Gas bubbles in the eluent lead to an unstable baseline, as high pressure
pumps can transport liquids, but not gases. The eluent therefore has to be
degassed, before it reaches the high pressure pump.
The eluent degasser removes gas bubbles and dissolved gases from the
eluent. For degassing, the eluent flows into a vacuum chamber through a
special fluoropolymer capillary.
Note
The eluent degasser is already installed in the newly delivered instru-
ment. The following installation instructions need
not
be carried out at
the time of initial installation.
