3.11 Inline filter
Between the purge valve and the pulsation absorber the inline filter
(6.2821.120) is installed as protection against particles.
Inline filters protect the separation column securely against possible con-
tamination from the eluent. Inline filters can however also just as well be
used for the purpose of protecting the suppressor against contaminations
in the regeneration or rinsing solutions. The filter platelets with a pore size
of 2 µm can be replaced quickly and easily. They remove particles like e. g.
bacteria and algae from the solutions.
Note
The inline filter is already installed in the newly delivered instrument.
The following installation instructions need not be carried out at the
time of initial installation.
