3.2.3 EOX determination
The EOX parameter is the sum of organically bound halogens (chlorine, bromide,
iodine) extracted under defined conditions from a water sample or from solids (sludge
and sediment) using an organic solvent. Hexane, heptane, pentane or petroleum ether
are used for extraction.
After extraction, the extract is combusted in the argon/oxygen stream. The hydrogen
halides produced will then be absorbed in the electrolyte solution before the halide
ions are determined argentometrically.
3.2.4 POX determination
The parameter POX is the sum of predominantly volatile organically bound halogens
(chlorine, bromine, iodine) which are purged from an aqueous sample under defined
conditions. These are thus separated from the aqueous phase without further
enriching in the gaseous phase. The gas used for purging is argon.
After purging, the separated material is combusted in the argon/oxygen stream. The
hydrogen halides produced will then be absorbed before the halide ions are
determined argentometrically.
3.3 System design
The standard version of the analyzer is composed of the following components:

multi X 2500 with combustion system

chlorine module (detector)

PC with multiWin software for device control and data analysis
The standard version of the multi X 2500 uses the vertical operating mode and the
"sensitive" measuring cell for determining the sum of adsorbable organic halogenated
compounds (AOX). There is the option to equip the multi X 2500 with the
autosamplers autoX 36, autoX 36d or autoX 112.
The optional horizontal operating mode requires an extension kit with multi-purpose
combustion tube and an additional boat feeder.
A self-check system (SCS) is integrated into the multi X 2500. The SCS is a
combination of hardware components and software functions that independently
ensure the error-free operation of the entire analysis system. The SCS verifies all
parameters relevant for the device's safety and the quality of the analysis several times
per second (e.g. gas flows, temperatures, pressures, signal drifts, cooling time, flame
value etc.).
