1 Introduction
1.1 Instrument description
The 930 Compact IC Flex is a professional ion chromatograph. It is distinguished by:
￭ Its intelligence: All of the functions are monitored, optimized and
documented 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 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 emissions.
￭ The intelligent MagIC Net™ software
1 Introduction
The 930 Compact IC Flex is operated solely 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 automatically and checks its functionality. The software controls and monitors
the instrument, evaluates the measured data and manages it in a database.
The 930 Compact IC Flex ChS consists of the following modules:
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.
High-pressure pump
The intelligent and low-pulsation high-pressure pump pumps the eluent
through the system. It is equipped with a chip where its technical specifications and "life history" (operating hours, service data, etc.) are saved.
Inline filter
Inline filters protect the separation column reliably from potential contamination 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.

1.2 Intended use
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
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 separation column with the eluent.
Suppressor
The suppressor consists of a suppressor drive, a rotor and, where applicable, an adapter. The suppressor drive gives you the flexibility to use different 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 according 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 substances. Knowledge with respect to the application of the fire prevention
measures prescribed for laboratories is also mandatory.

with the separately packed accessories. Keep this packaging, as only this
ensures safe transportation of the instrument.
3.1.2 Checks
Immediately after receipt, check whether the shipment has arrived complete and without damage by comparing it with the delivery note.
3.1.3 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 fluctuations and direct sunlight.
3.2 Capillary connections in the IC system
Generally speaking, capillary connections between two components of an
IC system are made up of one connection capillary and two pressure
screws used to connect the capillary to the respective components.
Pressure screws
Three types of pressure screws are used in the IC system:
Number
6.2744.010 / 6.2744.014 Pressure screw On the injection valve
6.2744.070 Pressure screw, short High-pressure pump, purge
Designation Use
valve, inline filter, pulsation
absorber, separation columns
6.2744.090 Pressure screw, long MCS, sample degasser, 12port valve
Pressure screws are tightened and loosened by hand. A tool is not
needed.

3 Installation
Also see: PEEK pressure screws video on the Internet http://ic-
help.metrohm.com/maintenance.php?chapter=1_2.
Connection capillaries
PEEK capillaries and PTFE capillaries are used in the IC system.
PEEK capillaries (polyetheretherketone)
PTFE capillaries
(poly(tetrafluoroethylene))
PEEK capillaries are temperature-resistant up to 100 °C, stable under pressure up to 400 bar (depending on the inner diameter), flexible, chemically
inert and have an extremely smooth surface. They can be readily cut down
to the desired length with the capillary cutter (6.2621.080).
Use:
￭ PEEK capillaries with an inner diameter of 0.25 mm (6.1831.010) for
the entire high-pressure section.
￭ PEEK capillaries with an inner diameter of 0.75 mm (6.1831.030) for
sample processing in the ultratrace range.
PTFE capillaries are transparent and enable visual tracing of the liquids to
be pumped. They are chemically inert, flexible and temperature-resistant
up to 80 °C. They can be readily cut down to the desired length with the
capillary cutter (6.2621.080).
Use:
PTFE capillaries (6.1803.0x0) are used for the low-pressure section.
￭ PTFE capillaries with an inner diameter of 0.5 mm for sample process-
ing.
￭ PTFE capillaries with an inner diameter of 0.97 mm for sample process-
ing and rinsing solutions (they are not necessarily included in the scope
of delivery of the instrument).
Capillary connections
If you work with an increased system pressure (> 15 MPa), capillaries
may slip out of the pressure screws.
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 capillaries
before connecting them with the pressure screws.
In order to achieve optimum analysis results, capillary connections in an IC
system must be absolutely tight and free of dead volume. Dead volume
occurs if two capillary ends connected to each other do not fit exactly,
thus allowing liquid to escape. There are two possible causes for this:
930 Compact IC Flex ChS (2.930.1200)
NOTE
￭￭￭￭￭￭￭￭
13
3.2 Capillary connections in the IC system
￭ The capillary ends do not have exactly flat edges.
￭ The two capillary ends do not completely meet.
One prerequisite for dead-volume-free capillary connection is that both
capillary ends are cut exactly flat. Therefore we recommend cutting PEEK
capillaries only with a capillary cutter (6.2621.080).
Also see: Cutting capillaries video on the Internet http://ic-
help.metrohm.com/maintenance.php?chapter=1_1.
Creating dead-volume-free capillary connections
To create dead-volume-free capillary connections, proceed as follows:
1
2
3
4
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Wipe off the end of the capillary with a cloth dampened with acetone.
Slide the pressure screw over the capillary. Ensure that the capillary
protrudes 1 to 2 mm from the tip of the pressure screw.
Push the capillary into the connection or coupling as far as it will go
and hold it there.
Only then start turning the pressure screw.
Colored sleeves for PEEK capillaries
The enclosed set of varicolored sleeves for PEEK capillaries (6.2251.000)
serves to easily differentiate the various flows of liquid in the system
through color coding. Each capillary conveying a given liquid (e.g. eluent)
can be marked with sleeves of the same color.
Slide a sleeve of a selected color over a capillary and move it to an
1
easily visible position.
Heat the colored sleeve, such as with a hairdryer.
2
The colored sleeve shrinks and adapts to the shape of the capillary.
NOTE
In order to arrange capillaries more clearly, they can be bundled with
the spiral band (6.1815.010).

3.3 Removing transport locking screws
To avoid damage to the drives for the high-pressure pump and the vacuum pump during transport, the pumps are secured with transport locking screws. These are located at the rear of the instrument and labeled
with Transport security screws.
Remove these transport locking screws before the initial start-up.
Accessories For this step you need:
￭ Hex key 4 mm (6.2621.030)
Remove the transport locking screws

3.4 Connecting the drainage tubing and leak sensor
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
CAUTION
The pumps may be damaged if you transport the instrument without
inserting the transport locking screws.
3.4 Connecting the drainage tubing and leak sensor
The leak sensor detects leaking liquid that collects in the instrument's base
tray. Liquid that leaks in the bottle holder or in the detector chamber is
routed to the base tray using drainage tubing and is detected there.
If the leak sensor detects a leak in the IC system, the IC instrument is
switched off and a warning is output in the software.
The leak sensor functions properly only if the following preconditions are
met:
￭ The drainage tubing is connected.
￭ The leak sensor connection cable is inserted into the leak sensor con-
nection socket.
￭ The 930 Compact IC Flex is switched on.
￭ The leak sensor is switched to active in the software.
3.4.1 Installing the drainage tubing
Liquid that leaks in the bottle holder or detector chamber flows to the rear
of the instrument and is drained through openings on the bottle holder
and in the detector chamber. The drainage tubing has to be mounted at
these openings. This drainage tubing guides the leaking liquid to the base
tray where the leak sensor is located.
Accessories
For this step you need the following parts from the accessory kit: Vario/

Mounting the adsorber tube
NOTE
Depending on the eluent used, the adsorber tube (6.1609.000)
must be filled differently:
￭ For alkaline eluents or eluents with a low buffer capacity: first a
little cotton, then CO2 adsorber material.
￭ For all other eluents: only cotton.
￭ Remove the plastic cover from the large opening of the adsorber
tube. Fill the adsorber tube and close it again using the plastic
cover.
