Functional principle
of trace SN cube
The trace SN cube is the world's most sensitive
combustion analyzer for sulfur and nitrogen
in diesel, gasoline and related samples. The
catalyst-supported digestion technology
ensures complete digestion of all kinds of
samples without soot formation or insufl-
cient recovery. The sample is always injected
directly into the combustion tube, there is no
need for time-consuming boat inlet feeding.
Thus, the analysis time is just 3-5 minutes,
depending on sample type. The trace SN cube
works as two analyzers in one box. The sample
is injected twice in diflerent combustion tubes
which allows the specic optimization of the
oxidation process for each element.
CATALYST SUPPORTED COMBUSTION
A well-known problem in high temperature
combustion of oil and petrochemical
samples is soot formation, caused by
incomplete combustion. By using special
developed accelerants, the oxidation
process can be optimized dramatically.
Almost any sample can be ignited without
soot production at injection volumes up to
100?µl. This offers the customer a flexibility
in sample handling which is outstanding
in this class of analyzers. Also the main-
tenance efforts are drastically reduced.
OIL ANALYSIS BY HIGH
TEMPERATURE COMBUSTION
High temperature combustion for the
determination of sulfur and nitrogen is
still the matter of choice if sensitivity really
counts. No other method delivers equally
sensitive, matrix-independent results. By
means of UV fluorescence detection for
sulfur and chemiluminescence for nitrogen
determination, detection limits of as low as
10?ppb can be achieved without problems,
outperforming all competing techniques.
The trace SN cube works with two independent furnaces and
combustion tubes. Thus, it is possible to adjust all parame-
ters which may influence the results, such as temperature,
injection volume, injection speed etc. of both channels
completely independently. This results in an outstanding
sample flexibility at always highest precision.
The known problem of interference in UV fluorescence
detection by NO (higher N concentrations simulate too high
sulfur contents) is solved by means of Elementar's unique
N Excess module. SO
2 is collected at an adsorption column
and released after the decay of the signal caused by NO. This
technique allows the precise determination of 0.1mg/kg S
in the presence of more than 100mg/kg N.
True two channel operation
Unique N Excess module
High sensitive detection
High sensitive chemiluminescence and UV fiuorescence detectors
ensure utmost sensitivity: 6?ppb for sulfur and 15?ppb for nitrogen.
This ultra-trace detection power gives rise to uncompromised
analysis of sulfur and nitrogen even in samples of lowest con-
centrations. This ensures that the trace SN cube greatly exceeds all
requirements of international standards and gives conffdence to
fulffll expected tighter standard requirements in future.
Outstanding sample flexibility
Along with liquid injections the trace SN cube can be equipped
with gas, LPG or solids module for a variety of matrices. A
temperature controllable autosampler is also available which
allows the analysis of highly volatile samples. In addition, the
instrument can be easily retrofftted to measure liquid samples.
