the syringe.

￭ Turn off high pressure pump.
￭ Close rotary knob (19-7).
￭ Remove syringe (19-1) from the Luer connector (19-2).

3.11 Inline filter
Between the purge valve and the pulsation damper the 6.2821.120 inline
filter 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 fine 2 µm material of the
readily and easily replaceable filter platelets removes particles such as bac-
teria 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.

Caution

tion of the inline filter.
