872 Extension Module IC Module
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
1 Introduction
1.1 Instrument description
Existing 850 Professional IC instruments can be expanded to include additional functions by means of 872 Extension Modules. Every 850 Professional IC instrument can be supplemented with up to 3 extension modules.
The 872 Extension Module IC Module allows to extend an 850 Professional IC instrument by another IC Module complete with high pressure
pump, purge valve, inline filter, pulsation damper and injection valve.
The 872 Extension Module IC Module can be used wherever an additional IC Module is necessary.
With the 872 Extension Module IC Module, a one-channel low pressure
gradient instrument can this way be extended to a two-channel AnCat
instrument with low pressure gradient. All instruments with sample preparation can be extended to two-channel systems as well.
1 Introduction
In a system with photometric detection with a 886 Professional Thermostat/Reactor as column holder and thermostat and an 887 Professional
UV/VIS Detector, it is also possible to use the 872 Extension Module IC
Module for conveying reagents.
The extension module is operated with MagIC Net software, just like the
IC instrument. When it is connected to an 850 Professional IC instrument,
MagIC Net recognizes the extension module automatically and checks its
functional capability. It controls and monitors the unit IC instrument –
extension module, evaluates the measured data and administers it in a
database.
The 872 Extension Module – IC Module comprises the following components:
Eluent degasser
The eluent degasser removes gas bubbles and dissolved gases from the
eluent. For degassing, the eluent flows into a vacuum chamber through a
special fluoropolymer capillary.
High pressure pump
The intelligent and low pulsation high pressure pump pumps the eluent
through the system. It is equipped with a chip on which its technical specifications and "life history" (operating hours, service data, ... ) are saved.

1.2 Intended use
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Inline filter
Inline filters protect the separation column securely against possible contamination from the eluent. Inline filters can however also just as well be
used for the purpose of protecting other sensitive components against
contaminations in the solutions used. The fine 2 µm material of the readily
and easily replaceable filter platelets removes particles such as bacteria
and algae from the solutions.
Pulsation damper
The pulsation damper 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 and sample path through rapid
and precise valve switchover. A precisely measured amount of sample
solution is injected and rinsed with eluent onto the separation column.
1.2 Intended use
The present instrument is suitable for processing chemicals and flammable
samples. The usage of the 872 Extension Module therefore requires that
the user has basic knowledge and experience in the handling of toxic and
caustic substances. Knowledge with respect to the application of the fire
prevention measures prescribed for laboratories is also mandatory.
1.3 About the documentation
1.3.1 Content and scope

1.4.1 General notes on safety
Warning
This instrument may only be operated in accordance with the specifications 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.
1.4.2 Electrical safety
The electrical safety when working with the instrument is ensured as part
of the international standard IEC 61010.
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.

Protection against electrostatic charges
Warning
Electronic components are sensitive to electrostatic charges and can be
destroyed by discharges.
Always pull the mains cable out of the mains connection socket before
connecting or disconnecting electrical appliances on the rear panel of
the instrument.
1.4.3 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
connections. Damaged tubing ends lead to leakage. Appropriate tools
can be used to loosen connections.
1 Introduction
Check the connections regularly for leakage. If the instrument is used
mainly in unattended operation, then weekly inspections are mandatory.
1.4.4 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. laboratory
flue).
￭ Keep all sources of flame far from the workplace.
￭ Clean up spilled fluids and solids immediately.
￭ Follow the safety instructions of the chemical manufacturer.
1.4.5 Recycling and disposal
This product is covered by European Directive 2002/96/EC, WEEE – Waste
from Electrical and Electronic Equipment.

3 Assembly
3.1 General
3 Assembly
The extension modules are fitted directly to the 850 Professional IC instrument and connected with it via 6.2156.060 connection cable. Extension
modules have no power supply of their own, but rather draw the electricity they require from the instrument with which they are connected.
Up to three extension modules can be connected to an 850 Professional
IC instrument. The following restrictions are to be taken into account:
Restrictions
The 850 Professional IC instruments and their extension modules must not
have more than 4 identical components in common, i.e.:
￭ a maximum of 4 high pressure pumps,
￭ a maximum of 4 peristaltic pumps,
￭ a maximum of 4 injection valves,
￭ a maximum of 4 suppressors (MSM, SPM incl.),
BUT
￭ only a maximum of 3 degassers
￭ and a maximum of 3 CO
suppressors (MCS)
2
Note
If all 4 high pressure pumps are being used at once, then not all of
them are permitted to run at maximum flow for longer periods of time.
Extension modules can be mounted in the following setup versions:
￭ above, between instrument and bottle holder (3-A), or
￭ below, between instrument and base tray (3-B), or
￭ next to the instrument (3-C) with a separate 6.2061.110 base tray and
a 6.2061.100 bottle holder (to be ordered additionally). For this, the
longer 6.2156.070 connection cable (to be ordered additionally), is
necessary, too.

Position the extension module in such a way that the capillary connections
can be kept as short as possible. If several extension modules are used,
then they should all be installed in the same location if possible – either
above, below or next to the IC instrument. If this is not possible, then the
extension modules that are located at greater distances from one another
must be connected with one another by means of the longer 6.2156.070
connection cable (available as optional accessory).
