brochure du trace SN cube d'Elementar pour l'analyse ppb de soufre et azote

the very best in ppb analysis

• high sensitivity
• high data quality
• great flexibility
• extreme durability

• industry-leading performance and versatility
• detection limit of 6 ppb for sulfur
• detection limit of 15 ppb for nitrogen
• for liquids, LPG, gas and solid samples
• outstanding robustness
• up to 56 position autosampler

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 insufficient 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 different combustion tubes which allows the specific optimization of the oxidation process for each element.

functional principle of trace SN cube

• liquid sample injection
• sample carousel
• argon, oxygen, synthetic air
• combustion tube, furnace, combustion tube
• gas drying detection
• high sensitive detection
• high sensitive chemiluminescence and UV fluorescence 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 concentrations.
• this ensures that the trace SN cube greatly exceeds all requirements of international standards and gives confidence to fulfill expected tighter standard requirements in the 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 retrofitted to measure liquid samples.

unique n excess module

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. SO2 is collected at an adsorption column and released after the decay of the signal caused by NO. this technique allows the precise determination of 0.1 mg/kg S in the presence of more than 100 mg/kg N.

true two-channel operation

the trace SN cube works with two independent furnaces and combustion tubes. thus, it is possible to adjust all parameters 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.

trace analysis has never been easier!

sulfur nitrogen sample rsd [%] rsd [%] ease of use

• the trace SN cube is optimized to significantly simplify the daily routine operation. clearly arranged, easily accessible system components as well as a furnace that slides out minimize maintenance efforts. the tool-free clamp connection system ensures a reliably leak-tight instrument at any time. thus, customers can enjoy smooth analyses and confidence in their results.
