In detail
Modes
The trace SN cube is optimized for the analysis of:- SN
- S
- N
Analytical specifications
Sample volume
Injection volume free adjustable from 3-80 µl
Analysis time
~ 4-6 min per parameter, self-optimizing according to element content and sample weight. Depending on sample type, analysis mode, and configuration.
Element concentration range
Large measuring range:
S: up to 1,000 ppm, 6 ppb LOD
N: up to 1,000 ppm, 15 ppb LOD
Precision
< 2 % rel. for 10 ppm standard (S and N)
Technical specifications
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.
Purge and trap technique
This option allows users to enable the determination of very low S concentrations, even when N levels are high.
