2.1 Instrument description
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 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 Oven SeS/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.

2 Introduction
Column oven
The column oven regulates the temperature for the separation column
and the eluent, thereby providing stable measuring conditions. There is a
column holder with chip reader in the column oven.
Eluent degasser
The eluent degasser removes gas bubbles and dissolved gases from the
eluent.
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 specifications and "life history" (operating hours, service data, etc.) are stored.
Inline filter
Inline filters protect the separation column reliably from potential contamination 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 separation 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 flexibility 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 instrument'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.

2.2 Intended use
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Metrohm CO2 Suppressor (MCS)
The Metrohm CO2 Suppressor (MCS) removes the CO2 from the eluent
stream. This lowers the background conductivity, improves detection sensitivity 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.
Sample degasser
The sample degasser removes gas bubbles and dissolved gases from the
sample.
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, injections etc) are stored.
2.2 Intended use
The 930 Compact IC Flex Oven SeS/PP/Deg is used for the determination
of anions, cations or polar substances with sequential suppression using
ion chromatography.
Sequential suppression consists of:
￭ Chemical suppression with a Metrohm Suppressor Module (MSM) and
subsequent
￭ CO
2
Background conductivity is reduced to a minimum with sequential suppression.
The instrument can also be used as needed for the determination of cations, polar substances or anions without suppression.
This instrument is suitable for processing chemicals and flammable samples. Therefore, the use of the 930 Compact IC Flex requires the user to
have basic knowledge and experience in handling toxic and caustic substances. Knowledge regarding the application of fire prevention measures
prescribed for laboratories is also mandatory.

4 Installation
4.1 Setting up the instrument
4.1.1 Packaging
The instrument is supplied in protective packaging together with the separately 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 complete 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.
4 Installation
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.
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 chemicals.
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.
￭ 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

4.3 Removing transport locking screws
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:
￭ 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.
Creating dead-volume-free capillary connections
To create dead-volume-free capillary connections, proceed as follows:

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. Hold the capillary in the
stop position while turning it shut.
4.3 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.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
4.4 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
conveyed 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. The software displays a warning.
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.
4.4.1 Installing the drainage tubing
Liquid that leaks in the bottle holder or detector chamber flows to the rear
of the instrument. Openings on the bottle holder and in the detector
chamber allow the liquid to drain. 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.
