The trace SN cube allows the analysis of S, N and SN analysis in organic liquids, with Cl analysis functionality optional in combination with the others. Compatibility with gaseous and solid samples is also optional.
Detection of S is performed using UV-fluorescence, while N analysis is supported by chemiluminescence detection.
The trace SN cube offers high-temperature combustion in the carrier gas at up to 1,150°C, with direct injection of liquid samples into separate ports for N and S determination.
Two instruments in one
Two completely separate combustion and detection channels are included for S and N, offering ideal analytical conditions and catalysts for each analysis without any compromise. This delivers all of the benefits of two separate analyzers, without the additional cost or space requirements this would involve.
Efficient injection methods
The instrument offers a maximum injection volume of 80 µl for liquids or 10 ml for gas samples. Injection times are only a few seconds, offering complete and residue-free combustion results in especially sharp peaks.
Purge and trap technique
This option allows users to enable the determination of very low S concentrations, even when N levels are high.
Highly sensitive detection
The instrument’s CLD and UV-fluorescence detection methods adhere to ASTM standards and deliver accurate, reliable results.
Broad measuring range
S and N levels can be measured between a range of zero and 1,000 ppm. Detection limits are set at 6 ppb for S and 15 ppb for N.
Compliance with industry standards
The system operates according to verified standards including ASTM D 6920, ASTM D 4629, ASTM D5453, ASTM D6667, DIN ISO 51444, ASTM D6069 and DIN ISO 20846.
Automated liquid feeding with a 50-position autosampler or a temperature-controllable 56-position autosampler, offering programmable cleaning cycles. Both are refillable even during analysis runs.
Chlorine detection option
Detection of chlorine can be added on with a sensitive electrochemical detector set, including a combustion tube for optimized Cl recovery, a drying device and the detector itself.
An LPG sampler is available for the injection of gaseous samples or liquified petroleum gas samples.
Solids analysis modules
Add-on modules are available for the analysis of solid samples, including a manual feeding option and an automated feeding system that includes an 80-position or 120-position carousel.
For the determination of low S concentrations at high N contents.
The basic setup contains the necessary resources to support the initial installation and approximately 1,000 analyses after that.
