Function and layout of the compEAct S compEAct S

3 Function and layout of the compEAct S

3.1 Principle of operation

The compEAct S is a compact elemental analyzer for determining sulfur contents in

liquid samples. The separately available LPG module 2.0 allows feeding the analyzer
with pressurized liquefied gas samples (LPG). The combined GSS/LPG module allows
feeding the analyzer with both LPG samples and pressurized gaseous samples.
The samples are digested at temperatures between 1000 and 1100 °C in a two-stage
process consisting of a pyrolysis followed by thermal oxidation. During the first phase
of the digestion the sample components are vaporized or pyrolized in the Argon flow
and the generated pyrolysis gases incinerated in the oxygen flow. Next the remaining
pyrolysis products are re-incinerated in the pure oxygen flow during the second phase.
The digestion can be summed up by the following equation:
R* - S + O2 → SO2 + CO2 + H2O
R*... = residual hydrocarbons

The sample aliquot (liquid, gaseous, LPG) is metered directly into the combustion tube
within the sample introduction module (autosampler LS, auto-injector AI, LPG
module 2.0, combined GSS/LPG module) via the injection port with septum
After leaving the combustion tube the reaction gas mix is fed to the measuring gas
drying process. The measuring gas is dried in a membrane dryer. The dried measuring
gas is fed to the UV fluorescence detector (UVFD).

Fig. 2 Principle of operation

The detection is done using the UV fluorescence method. This principle is based on the
fact that SO2, which is excited by UV light, emits a characteristic fluorescence radiation

16
compEAct S Function and layout of the compEAct S

in the range of 220 to 420 nm. This fluorescence radiation is measured. The changes
in the intensity of the fluorescence are then used to calculate the SO2 concentration.

3.2 Layout of the compEAct S

Main components of the The compEAct S consists of the following main components:
compEAct S
 Electronics
 Internal computer with touchscreen
 Gas supply
 Combustion system
 Auto-protection assembly (APB)
 Measuring gas dryer
 UV fluorescence detector
 Sample introduction system
All components of the compEAct S to be operated or serviced by the user can be
reached via the front door and the opening at the top of the device.

Function and layout of the compEAct S compEAct S

The two process gases argon and oxygen are controlled via the gas box in the
compEAct S. The gas box does not require any maintenance from the user.
The compEAct S is a stand-alone device with integrated computer. The control and
analysis software EAvolution is operated via the touchscreen on the right-hand side of
the device.
Combustion system In the compEAct S a resistor-heated combustion furnace is used for digestion
temperatures between 700 °C and 1100 °C. Depending on the application, the samples
are digested inside the combustion tube at temperatures between 950 °C and 1100 °C.
A combustion tube has been inserted into the combustion furnace of the compEAct S
which is used for all standard applications. The combustion tube is made of quartz
glass. A quartz wool plug inserted in the inner tube ensures a slow and steady
vaporization of the sample. The connection between the combustion tube and the
measuring gas dryer is implemented via the auto-protection assembly.
