2 Introduction
2.1 Instrument description
The 930 Compact IC Flex is a robust ion chromatograph. It is distinguished
by:
￭Its intelligence: All of the functions are monitored, optimized and docu-
mented in an FDA-compatible manner. Intelligent components, such as
iColumns, save important data onto a chip.
￭Its compact design: It has a small footprint.
￭Its transparency: All components are easily accessible and located for
simple visibility and can be monitored during operation through a large
window.
￭Its safety: The wet end and the electronics are physically separated,
thereby preventing fluids from coming into contact with the electronics
to a large extent. A leak sensor is integrated into the wet end.
￭Its environmental compatibility.
￭Its low noise emission.
￭The intelligent MagIC Net software.
The 930 Compact IC Flex is operated using the MagIC Net software. A
USB cable is used to connect the instrument to a computer with
MagIC Net installed. The intelligent software detects the instrument auto-
matically and checks its functionality. The software controls and monitors
the instrument, evaluates the measured data and manages it in a data-
base.
The 930 Compact IC Flex ChS/PP/Deg consists of the following modules:
Housing
The sturdy housing contains the instrument's electronic components,
including their interfaces and one connector for a separation column. In
addition, the housing provides space for a conductivity detector or an
amperometric detector. Capillaries and cables can be fed into and out of
the instrument through several openings.
Leak sensor
The leak sensor detects leaking liquid that collects in the instrument's base
tray. Liquid that leaks in the instrument is routed to the base tray using
drainage tubing and detected there.
Eluent degasser
The eluent degasser removes gas bubbles and dissolved gases from the
eluent.

930 Compact IC Flex ChS/PP/Deg (2.930.1360) ￭￭￭￭￭￭￭￭ 3
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.
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.
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.

2.2 Intended use ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
4￭￭￭￭￭￭￭￭ 930 Compact IC Flex ChS/PP/Deg (2.930.1360)
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.
2.2 Intended use
The 930 Compact IC Flex ChS/PP/Deg is used for the determination of
anions or polar substances with chemical suppression using ion chroma-
tography.
It can also be used as needed for the determination of cations, polar sub-
stances or anions without chemical suppression.
This instrument is suitable for processing chemicals and flammable sam-
ples. Therefore, the use of the 930 Compact IC Flex requires the user to
have basic knowledge and experience in handling toxic and caustic sub-
stances. Knowledge regarding the application of fire prevention measures
prescribed for laboratories is also mandatory.
2.3 Safety instructions

WARNING
Never open the housing of the instrument. The instrument could be
damaged by this. There is also a risk of serious injury if live components
are touched.
There are no parts inside the housing which can be serviced or replaced
by the user.
Supply voltage
WARNING
An incorrect supply voltage can damage the instrument.
Only operate this instrument with a supply voltage specified for it (see
rear panel of the instrument).
Protection against electrostatic charges
WARNING
Electronic components are sensitive to electrostatic charges and can be
destroyed by discharges.
Do not fail to pull the power cord out of the power socket before you
set up or disconnect electrical plug connections at the rear of the
instrument.
2.3.3 Tubing and capillary connections
CAUTION
Leaks in tubing and capillary connections are a safety risk. Tighten all
connections well by hand. Avoid applying excessive force to tubing con-
nections. Damaged tubing ends lead to leakage. Appropriate tools can
be used to loosen connections.
Check the connections regularly for leakage. If the instrument is used
mainly in unattended operation, then weekly inspections are manda-
tory.

4 Installation
4.1 Setting up the instrument
4.1.1 Packaging
The instrument is supplied in protective packaging together with the sepa-
rately packed accessories. Keep this packaging, as only this ensures safe
transportation of the instrument.
4.1.2 Checks
Immediately after receipt, check whether the shipment has arrived com-
plete and without damage by comparing it with the delivery note.
4.1.3 Location
The instrument has been developed for operation indoors and may not be
used in explosive environments.
Place the instrument in a location of the laboratory which is suitable for
operation, free of vibrations, protected from corrosive atmosphere, and
contamination by chemicals.
The instrument should be protected against excessive temperature fluctua-
tions and direct sunlight.
4.2 Capillary connections in the IC system
Capillary connections
NOTE
Sprays of chemicals caused by capillaries slipping out
If you work with an increased system pressure (> 15 MPa), capillaries
may slip out of the pressure screws. This can lead to sprays of chemi-
cals.
To avoid this, we recommend
￭degreasing the ends of the capillaries before installing them.
Dampen a cloth with acetone and wipe off the ends of the capilla-
ries before connecting them with the pressure screws.
￭tightening the pressure screws firmly using a wrench (6.2739.000).
In order to achieve optimum analysis results, capillary connections in an IC
system must be absolutely tight and free of dead volume. Dead volume
