In detail
Modes
The vario TOC cube is optimized for TOC/TNb analysis. The following modes are available:Liquid mode
The liquid mode offers different autosamplers for up to 80 sample positions. All positions can be stirred and purged. Alternatively, a cost-efficient solution with manual sample change is also available. The change between liquid mode and solid mode is very easy and takes only a few minutes.
Solid mode
The solid mode offers different autosamplers with up to 120 sample positions. Alternatively, a cost-efficient solution with manual sample change is also available. The change between liquid mode and solid mode is very easy and takes only a few minutes.

Large detection range
From low ppb to percent. Variable sample volume allows also multipoint calibration from a single standard solution with auto-dilution-effect. Extraordinary linearity over the entire calibration range.
SALTTRAP ensures low maintenance for salt-containing samples
The innovative combustion tube concept enables real matrix separation and offers maximum protection of the combustion tube. Leads to long lifetime and low running costs. Designed for analyses of salt-containing samples, particles, or other complicated sample matrices.
In accordance with official standards
The vario TOC cube operates in full compliance with all relevant standards for TOC, TC, TIC and TNb in liquid samples such as ISO 20236, ISO 8245, EN 1484, EN 12260, SM 5310B, EPA 415.1, and ASTM D7573. Due to the unique solids option, TOC and TC can also be determined in solids like soil or waste according to EN 15936 and ISO 10694.
Easy, compact, and economical
The unique instrument concept is characterized by easy handling and optimized for low maintenance costs – with high flexibility and analytical performance.

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.
Einfachste Probenvorbereitung: Minimierter Aufwand dank Tiegeltechnologie
- Einfache Analyse von Progeneinwaagen bis zu 3 g.
- Auch inhomogene Proben lassen sich zeitsparend einwiegen und präzise analysieren, da größere Probeneinwaagen den Aufwand für Homogenisierung deutlich reduzieren.
- Komfortable TOC-Messungen gemäß DIN EN 15936 mit direkter Ansäuerung der Probe im alternativen Keramiktiegel.
- Verringerte Kosten für Verbrauchsmaterialien durch wiederverwendbare Tiegel.
Unübertroffene Flexibilität: Anpassbar auf Ihre analytischen Anforderungen
- Optionale Bestimmung des Gesamtstickstoffs (TN) möglich.
- Die Analyse von Kohlenstoff in Flüssigkeiten ist für bestimmte Konzentrationen möglich.
- TOC400, ROC und TIC900 kann in nur einem Verfahrensschritt bestimmt werden. Hierzu werden die unterschiedlichen Bindungsformen des Kohlenstoffs mittels Temperaturrampe aus unterschiedlichen Zieltemperaturen unter oxidativen und pyrolytischen Bedingungen unterschieden.
- Alternativ kann auch das klassische Verfahren mittels Ansäuerung zur TIC Entfernung, Trocknung und anschließender TOC-Messung durchgeführt werden.
- DIN 19539 und DIN EN 15936/ISO 10694 konforme Analysen mit nur einem Gerät möglich.
