1 Introduction
1.1 Instrument description
The instrument 882 Compact IC plus – Anion is one of the model ver-
sions of the 882 Compact IC plus line of instruments manufactured by the
Metrohm Company. The 882 Compact IC plus line of instruments is distin-
guished by:
￭the intelligence of its components, which are able to monitor and
optimize all functions and to provide documentation according to FDA
requirements.
￭its compact style of construction.
￭its transparency. All components are easily accessible and arranged in
a clear manner.
￭its safety. Chemicals and electronics are separated and a leak sensor is
integrated in the wet end.
￭its environmental compatibility.
￭its low noise emission.
The instrument is operated with MagIC Net™ software. It is connected
via a USB connection to a PC on which MagIC Net™ is installed. The soft-
ware automatically recognizes the instrument and checks its functional
readiness. MagIC Net™ controls and monitors the instrument, evaluates
the measured data and administers it in a database. The operation of
MagIC Net™ is described in the online help or in the tutorial for
MagIC Net™.
The instrument contains the following components:
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 spec-
ifications and "life history" (operating hours, service data, … ) are saved.
Inline filter
Inline filters protect the separation column securely against possible con-
tamination 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 filter platelets with a pore size
of 2 µm can be replaced quickly and easily. They remove particles like e. g.
bacteria and algae from the solutions.

1.2 Intended use ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
2￭￭￭￭￭￭￭￭ 882 Compact IC plus – Anion
Pulsation absorber
The pulsation absorber 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.
Peristaltic pump
The Peristaltic pump is used for pumping sample and auxiliary solutions. It
can rotate in both directions.
Metrohm Suppressor Module (MSM)
The MSM is used for chemical suppression in anion analysis.It is pressure-
stable, robust and resistant to solvents.
Separation column
The intelligent separation column is the heart of the ion chromatographic
analysis. It separates the different components corresponding to their
interactions with the column. Metrohm separation columns are equipped
with a chip on which their technical specifications and their history (first
use / setting up, operating hours, injections, …) are saved.
1.2 Intended use
The instrument 882 Compact IC plus – Anion is used for the ion chro-
matographic determination of anions or polar substances with chemical
suppression by the Metrohm Suppressor Module (MSM) (see Chapter
3.14, page 42). If required, it can also be used for the determination of
anions without chemical suppression or for the determination of cations.
This instrument is suitable for processing chemicals and flammable sam-
ples. The usage of the 882 Compact IC plusAnion 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.

1.4 Safety instructions
1.4.1 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.

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.

882 Compact IC plus – Anion ￭￭￭￭￭￭￭￭ 5
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.
Check the connections regularly for leakage. If the instrument is used
mainly in unattended operation, then weekly inspections are manda-
tory.
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.
The correct disposal of your old equipment will help to prevent negative
effects on the environment and public health.
