High-pressure pump
The intelligent and low-pulsation high-pressure pump pumps the eluent
through the IC system. It is equipped with a chip where its technical speci-
fications and "life history" (operating hours, service data, etc.) are stored.
Inline filter
Inline filters protect the separation column reliably from potential contami-
nation from the eluent. The filter pads with 2 µm pore size can be
replaced quickly and easily. They remove particles from the solutions, such
as bacteria and algae.
Pulsation absorber
The pulsation absorber 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.
Injection valve
The injection valve connects the eluent path to the sample path. By a
quick and precise switching of the valve, a quantity of sample solution
defined by the size of the sample loop is injected and flushed to the sepa-
ration column with the eluent.
Detector
Metrohm offers a series of different detectors for various analysis tasks. A
suitable detector type must be ordered as a separate device.
Sample degasser
The sample degasser removes gas bubbles and dissolved gases from the
sample.
Separation column
The intelligent separation column separates different components accord-
ing to their interactions with the column. Metrohm separation columns
are equipped with a chip where their technical specifications and history
(start-up, operating hours, injections etc) are stored.
