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).

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:

NOTICE
Do not mix these up!
￭Absorber solution: e.g. H2O2 solution for oxidizing sulfur oxides.
￭Absorption solution: Combustion gases dissolved in the absorber
solution.
The determination is controlled entirely by MagIC Net. You can find a
detailed description of the sequence in the online help for MagIC Net
under the title "Combustion sequence".
