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.
￭Its performance: Short retention times and sharp peaks when used
with the IC Conductivity Detector MB and a column with a diameter of
2 mm.
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/Deg/MB 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.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 2 Introduction
930 Compact IC Flex Oven/Deg/MB (2.930.2180) ￭￭￭￭￭￭￭￭ 3
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 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.
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 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.

8￭￭￭￭￭￭￭￭ 930 Compact IC Flex Oven/Deg/MB (2.930.2180)
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.
