1 About these short instructions
These Short Instructions contain important information about the Com-
bustion IC system. In addition to an introduction and safety instructions,
you can find a description of the Combustion IC system and information
on installing the 920 Absorber Module and its interfaces to the Combus-
tion-IC-System. You can download the detailed manual for the 920
Absorber Module as a PDF file from the Internet
(https://www.metrohm.com).

2 Introduction
2.1 The Combustion IC system
2.1.1 Overview
Combustion is a sample preparation technique that uses burning to digest
a sample. Solid, liquid and gaseous samples that are flammable can be
digested using combustion. Combustion IC is particularly suited for deter-
mining the following elements:
Figure 1 Detectable elements
An additional instrument is required for the determination of gaseous
samples: the LPG/GSS Module (AJ) (2.136.0720) or the GLS Sampler CIC
(TEI) (2.0136.0630).

Combustion-IC-System ￭￭￭￭￭￭￭￭ 3
2.1.2 System description
Figure 2 Overview – CIC system
The sample is combusted in the Combustion Module (AJ) / Combustion
Oven (TEI).
The gases generated during combustion are dissolved into an absorber
solution in the 920 Absorber Module and are optimized for analysis using
suitable sample preparation techniques.
In the end, the absorption solution is preconcentrated in an ion chromato-
graph and analyzed.
The entire process is controlled and monitored using MagIC Net software.
The analysis data is saved in the software's database.
2.1.3 Sequence of a determination
A determination in the Combustion IC system runs according to the fol-
lowing diagram:

2.2 Intended use
The present system is suitable for processing chemicals and flammable
samples. Usage of the Combustion IC system therefore requires the user
to have basic knowledge and experience in handling toxic and caustic
substances. Knowledge regarding the application of fire prevention meas-
ures prescribed for laboratories is also mandatory.
2.3 Safety instructions
2.3.1 General notes on safety
WARNING
Operate this instrument only according to the information contained in
this documentation.
This instrument 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.
2.3.2 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.
There are no parts inside the housing which can be serviced or replaced
by the user.

2.3 Safety instructions ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
6￭￭￭￭￭￭￭￭ Combustion-IC-System
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.
2.3.3 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.

2.3.4 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.
2.3.5 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.
