2.1 Instrument description ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
2￭￭￭￭￭￭￭￭ 930 Compact IC Flex SeS (2.930.1400)
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.
This prevents 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 device to a computer with MagIC Net
installed. The intelligent software detects the device automatically and
checks its functionality. The software controls and monitors the device,
evaluates the measured data and manages it in a database.
The 930 Compact IC Flex SeS 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.
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.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 2 Introduction
930 Compact IC Flex SeS (2.930.1400) ￭￭￭￭￭￭￭￭ 3
Inline filter
Inline filters protect the separation column reliably from potential contam-
ination 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.
Metrohm CO2 Suppressor (MCS)
The Metrohm CO2 Suppressor (MCS) removes the CO2 from the eluent
stream. This lowers the background conductivity, improves detection sen-
sitivity 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.
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.

3.1 Intended use ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
6￭￭￭￭￭￭￭￭ 930 Compact IC Flex SeS (2.930.1400)
3 Safety
3.1 Intended use
The 930 Compact IC Flex SeS is used for the determination of anions, cati-
ons or polar substances with sequential suppression using ion chromato-
graphy.
Sequential suppression consists of:
￭Chemical suppression with a Metrohm Suppressor Module (MSM) and
subsequent
￭CO2 suppression with the Metrohm CO2 Suppressor (MCS).
Background conductivity is reduced to a minimum with sequential sup-
pression.
The instrument can also be used as needed for the determination of cati-
ons, polar substances or anions without 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.
3.2 Responsibility of the operator
The operator must ensure that basic regulations on occupational safety
and accident prevention in chemical laboratories are observed. The opera-
tor has the following responsibilities:
￭Instruct personnel in the safe handling of the product.
￭Train personnel in the use of the product according to the user docu-
mentation (e.g. install, operate, clean, eliminate faults).
￭Train staff on basic occupational safety and accident prevention regula-
tions.
￭Provide personal protective equipment (e.g. protective glasses, gloves).
￭Provide suitable tools and equipment to carry out the work safely.
The product may be used only when it is in perfect condition. The follow-
ing measures are required to ensure the safe operation of the product:

3.4 Safety instructions ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
8￭￭￭￭￭￭￭￭ 930 Compact IC Flex SeS (2.930.1400)
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.
3.4.3 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.
