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.

The pulsation absorber is completely connected. No installation work is
required.

Injection valve

The injection valve is completely connected. No installation work is
required.

Suppressor

The suppressor drive of the 940 Professional IC Vario can hold various
rotors. The large rotors such as the SPM Rotor A (6.2835.000) and the
MSM-HC Rotor A (6.2842.000) can be inserted directly.

Small rotors like the MSM Rotor A (6.2832.000) and the MSM-LC Rotor A
(6.2844.000) must first be fitted into the adapter (6.2842.020) which can
then be inserted into the suppressor housing.

A connecting piece (6.2835.010) is used for all rotors for connecting the
suppressor to the IC system.
