3.8 Installing the pulsation absorber
The pulsation absorber is installed between the high-pressure pump and
the injection valve. It protects the separation column from damage caused
by pressure fluctuations such as those when switching the injection valve,
and reduces interfering pulsations during highly sensitive measurements.
