3.14 Pulsation damper
NOTE
The pulsation damper is already installed in the newly delivered instru-
ment.
CAUTION
The pulsation damper is maintenance-free and may not be opened.
The pulsation damper 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 3.12, page 42) and injection valve (see
Chapter 3.16, page 50) .
The pulsation damper can be operated in both directions.
