930 Compact IC Flex ChS (2.930.1200)
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.
Detector
Metrohm offers a series of different detectors for various analysis tasks. A
suitable detector type must be ordered as a separate accessory.
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.
1.2 Intended use
The 930 Compact IC Flex ChS is used for the determination of anions or
polar substances with chemical suppression using ion chromatography.
It can also be used as needed for the determination of cations or anions
without chemical suppression.
The present instrument is suitable for processing chemicals and flammable
samples. Usage of the 930 Compact IC Flex therefore requires the user to
have basic knowledge and experience in handling toxic and caustic sub-
stances. Knowledge with respect to the application of the fire prevention
measures prescribed for laboratories is also mandatory.
