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.
