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:

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".
