930 Compact IC Flex ChS/PP/Deg (2.930.1360)
Inline filter
Inline filters protect the separation column reliably from potential contami-
nation from the eluent. The small 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 when switching the injection valve, 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.
Suppressor
The suppressor consists of a suppressor drive, a rotor and, where applica-
ble, an adapter. The suppressor drive gives you the flexibility to use differ-
ent rotors according to the principle "one drive – many rotors". With
appropriate adapters, the rotor for the sample preparation module (SPM
Rotor) or suppressor rotors with different capacities and construction can
be easily exchanged. The rotors are not included in the instrument's scope
of delivery. A rotor suitable for the application must be ordered separately.
Peristaltic pump
The peristaltic pump is used for pumping sample and auxiliary solutions. It
can rotate in both directions.
Detector
Metrohm offers a series of different detectors for various analysis tasks. A
suitable detector type must be ordered as a separate accessory.
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, etc) are stored.
