930 Compact IC Flex Oven/ChS/Deg (2.930.2260) ￭￭￭￭￭￭￭￭ 1
1 Introduction
1.1 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 Oven/ChS/Deg consists of the following mod-
ules:
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.

1.1 Instrument description ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
2￭￭￭￭￭￭￭￭ 930 Compact IC Flex Oven/ChS/Deg (2.930.2260)
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 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.
Detector
Metrohm offers a series of different detectors for various analysis tasks. A
suitable detector type must be ordered as a separate device.

930 Compact IC Flex Oven/ChS/Deg (2.930.2260) ￭￭￭￭￭￭￭￭ 3
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, injections etc) are stored.
1.2 Intended use
The 930 Compact IC Flex Oven/ChS/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.
1.3 Safety instructions
1.3.1 General notes on safety
WARNING
This instrument may only be operated in accordance with the specifica-
tions in this documentation.
This instrument has left the factory in a flawless state in terms of technical
safety. To maintain this state and ensure non-hazardous operation of the
instrument, the following instructions must be observed carefully.
1.3.2 Electrical safety
The electrical safety when working with the instrument is ensured as part
of the international standard IEC 61010.

4￭￭￭￭￭￭￭￭ 930 Compact IC Flex Oven/ChS/Deg (2.930.2260)
WARNING
Only personnel qualified by Metrohm are authorized to carry out service
work on electronic components.
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.

1.3.3 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.
1.3.4 Flammable solvents and chemicals
WARNING
All relevant safety measures are to be observed when working with
flammable solvents and chemicals.
￭Set up the instrument in a well-ventilated location (e.g. fume cup-
board).
￭Keep all sources of flame far from the workplace.
￭Clean up spilled liquids and solids immediately.
￭Follow the safety instructions of the chemical manufacturer.
1.3.5 Recycling and disposal
This product is covered by European Directive 2012/19/EU, WEEE – Waste
Electrical and Electronic Equipment.
The correct disposal of your old instrument will help to prevent negative
effects on the environment and public health.
More details about the disposal of your old instrument can be obtained
from your local authorities, from waste disposal companies or from your
local dealer.
