ELTRA
Precise carbon and sulfur
analysis in inorganic samples
The CS-800 by Eltra, Haan, Germany,
is a flexible and robust combustion
analyzer for the determination of carbon
and sulfur in inorganic sample
materials such as steel, cast iron or cement.
Organic samples like soil, graphite
or chemicals can also be analyzed
with the CS-800. It is equipped with
a 2,500 °C induction furnace to examine
the element concentrations in
solids without time-consuming sample
preparation. The typical analysis
time is approximately 45 to 60 s.
Whereas spectrometric methods require
a homogeneous and plane sample
surface for C/ S analysis, the CS-800
also accepts samples in the form of
powders, grains, drillings or broken

pieces. Thanks to the high sample
weight of up to 1 g even inhomogeneous
samples can be reliably characterized.
The CS-800 features up to four independent
infrared measuring cells allowing
for accurate analysis of low as
well as high carbon and sulfur concentrations
simultaneously in one measurement.
The sensitivity of the IR cells
can be individually configured to ensure
optimum adaptation to application
requirements. If the analysis involves
aggressive reactive gases (for
example from acidulous soil samples)
the use of robust and durable gold cuvettes
is an option.

and sulfur in a 2,500 °C induction
furnace
» Up to four independent infrared cells
with flexible measuring ranges
» Very short measurement times
» High sample weights from a few milligrams
to 1 gram
» Flexible sample geometry
