Modes
The soli TOC cube is optimized for TOC analysis. The following modes are available:Solid mode
The solid mode offers TOC, TOC400, TIC, TIC900, TC and ROC determination in solid samples with an autosampler for up to 89 sample positions.
TN mode
Simultaneous nitrogen determination with robust electrochemical detection.
Analytical specifications
Analysis method
True temperature ramping in an oxygenated atmosphere up to 900 °C for TOC400, ROC and TIC900 determination in solids compliant with EN 17505 and DIN 19539. Alternative gas switching for combination of oxidizing and non-oxidizing carrier gases in one course to separate ROC and TIC900. Catalytic combustion for the determination of TOC in solids compliant with EN 15936. Option for simultaneous TN determination with ECD.
Easy sample preparation and handling
Without any special sample preparation, all kinds of solid samples are weighed into steel or ceramic sample crucibles (sample mass up to 3 g).
In accordance with official standards
The soli TOC cube operates in full compliance with all relevant national and international norms or standards such as EN 17505, DIN 19539, EN 15936, ISO 10694, and EN 13137.

Unmatched analytical performance:
Limit of detection (LOD) of 10 ppm or < 15 μg C
- The soli TOC® cube is the most sensitive instrument in the market and offers an unmatched measurement range from 0.001 – 100 % carbon.
- Reproducible measurements due to precise adjustable temperature with fast heating rates. Temperature is measured where it matters, directly at the crucible.
- Consistent high measurement quality thanks to the use of a post-combustion catalyst. This ensures that even high carbon-content samples are quantitatively oxidized.
- Optimized separation of residual organic carbon (ROC) and total inorganic carbon (TIC) for special samples thanks to integrated carrier gas switching.
Fast & easy analyses: Autosampler for 24/7 operation & automated ash removal
- Autosampler with 89 positions, optimized for unattended 24/7 high-throughput operation.
- Minimized efforts for sample preparation due to the advanced temperature ramping and the crucible technology.
- Automated ash removal and clearly arranged, easily accessible system components minimize maintenance efforts.
Simplified sample preparation: Minimized efforts with advanced crucible technology
- Easy analysis of samples up to 3 g.
- Even inhomogeneous samples can be prepared time-saving and analyzed precisely thanks to the large weights that minimize the need for homogenization drastically.
- Comfortable measurement of TOC according to EN 15936 with direct acidification in the alternative ceramic crucible.
- Reduced costs for consumables due to reusable crucibles.
Unsurpassed measurement flexibility: Adaptable to your analytical needs
- Optional total nitrogen (TN) determination possible.
- The analysis of carbon in liquids at a certain concentration level can also be performed.
- TOC400, ROC, and TIC900 can be determined in one single program. To do so, the different forms of carbon in solids can be distinguished by either temperature programming or a temperature program combined with gas switching.
- Alternatively, the classical method of TOC analysis after pre-acidification for TIC removal and drying is also possible.
- DIN 19539 and EN 15936/ISO 10694 compliant analyses can be performed within only one instrument.
User-friendly maintenance: Comfortable & tool-free
- Fast maintenance thanks to clearly arranged, easily accessible system components and tool-free clamp connections.
- The automated ash removal in combination with the outstanding robustness and longevity of the instrument reduce efforts for maintenance and repairs.
- Leak tight instrument at any time thanks to the tool free-clamp connection system.
