Inline filters protect the separation column reliably from potential contam-
ination from the eluent. The small filter pads with 2 µm pore size can be
replaced quickly and easily. They remove particles from the solutions.
The inline filter is completely connected. No installation work is required.
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, e.g. when the injection valve is switched, and
reduces interfering pulsations during highly sensitive measurements.
