Figure 17 Connecting the inline filter
1 Connection capillary
Connects the purge valve with the inline fil-
ter 2 PEEK pressure screws, short
(6.2744.070)
3 Inline filter (6.2821.120)
Protects against particles. 4 Connection capillary
Connects the inline filter with the pulsation
absorber.
1 Screw on the connection capillary running from the purge valve to
the input side of the inline filter using a pressure screw (6.2744.070).
2 Screw on the connection capillary running to the pulsation absorber
to the output side of the inline filter using a pressure screw
(6.2744.070).
3.12 Pulsation absorber
Note
The pulsation absorber is already installed in the newly delivered instru-
ment.
Caution
The pulsation absorber is maintenance-free and may not be opened.
The pulsation absorber protects the separation column from damage
caused by pressure fluctuations when switching the injection valve, and
reduces interfering pulsations during highly sensitive measurements. In
order to ensure these functionalities, it must be connected between the
high pressure pump (see Chapter 3.10, page 28) and injection valve (see
Chapter 3.13, page 34).
The pulsation absorber can be operated in both directions.
