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 contam-
ination 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.
Metrohm Suppressor Module (MSM)
The chemical suppressor MSM consists of the suppressor drive, a rotor
and, where applicable, an adapter. The suppressor drive gives you the flex-
ibility to use different rotors according to the principle "one drive – many
rotors". Suppression rotors with different capacities and construction or a
rotor for sample preparation (SPM Rotor) are readily interchangeable with
appropriate adapters as needed. The rotors are not included in the instru-
ment's scope of delivery. The rotor required for the application and any
adapter that is required must be ordered separately.
Peristaltic pump
The peristaltic pump is used for pumping sample and auxiliary solutions. It
can rotate in both directions.
Metrohm CO Suppressor (MCS)
2
The Metrohm CO Suppressor (MCS) removes the CO
2
stream. This lowers the background conductivity, improves detection sen-
sitivity and minimizes the injection peak and system peak.
Detector
Metrohm offers a series of different detectors for various analysis tasks. A
suitable detector type must be ordered as a separate device.
