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 4.6, page 29) and injection valve .
The pulsation damper can be operated in both directions.
