SPACE-SAVING
autosampler integrated
in instrument
The elements sulfur and nitrogen are found in low concentrations in hydrocarbons such as gasoline, diesel or natural gas. The new trace SN cube continues the success of the vario TRACE S/N liquid injection on the already approved cube platform.
The newly developed autosampler in combination with the time-proven combustion technique makes it an outstanding analyzer for the most sensitive determination of sulfur and nitrogen.
Two complete separate combustion and detection channels are incorporated into one analyzer, sharing just the liquid automatic injector (making two separate injections) and electronic control and processing. This allows the ideal analytical conditions and catalysts to be used for each analysis without any compromise.
It also results in significant cost and space savings compared to two separate analyzers. The methods are according to ASTM D 5453, D 6667, D 4629 and DIN ISO 20846. Trace analysis with safe and fully automatic operation.
S, N and SN mode (Cl optional in combination with the others) for organic liquids. Gaseous and solid samples optional.
Detection of S by UV-Fluorescence and N by Chemoluminescence detection.
Measuring method:
Direct injection of liquid samples in separate ports for N and S determination. Combustion in the carrier gas up to 1150 °C.
Two instruments in one:
Two completely separate combustion and detection channels for S and N. The ideal analytical conditions and catalysts are used for each analysis without any compromise. This results in all the benefits of two separate analyzers without the additional cost or space requirements.
Max. injection volume of 80 µl liquid or 10 ml gas sample:
injection time of only a few seconds with complete and residue-free combustion results in especially sharp peaks
Purge-and-Trap-Technique:
optional available, enables the determination of very low S concentrations even at high N contents
Highly sensitive detection:
according to ASTM with CLD and UV-fluorescence.
Measuring range:
0-1000 ppm S and N
Detection limit 6 ppb S / 15 ppb N
