rapid CS cube

Carbon and sulfur analyzer

In detail

ModesAnalytical specificationsTechnical SpecificationsAccessories

Modes

The rapid CS cube is optimized for the analysis of:
  • CS
  • C
  • S
  • Cl*
  • TIC in solids*

* optionally available

Analytical specifications

Weighing range

Large weighing range:
The instrument’s range encompasses micro (< 1 mg) and macro (1 g) applications, depending on the sample type.

Precision

< 1 % relative (homogeneous substance), depending on sample type, analysis mode, and configuration

Element concentration range

Large dynamic concentration range:
C: up to 40 mg absolute, from 0 - 100 %
S: up to 20 mg absolute, from 0 - 100 %
Cl*: up to 1.2 mg, from 0 - 100 %

Analysis time

~ 3-5 min, self-optimizing according to element content and sample weight. Depending on sample type, analysis mode, and configuration.
* optionally available

Technical specifications

Quantitative high-temperature decomposition

The rapid CS cube functions at a permanent temperature near 1,200 °C, reaching 1,800 °C during combustion due to the combustion enthalpy of the tin capsules. In pure oxygen, the contained sulfur is fully converted into SO2 with 100 % recovery, even in the case of BaSO4. Carbon is converted to CO2 and detected by a real non-dispersive IR detector.

Sample introduction 

  • Integrated 60, 80*, or 120* positions autosampler (for solids and liquids in capsules), reloadable during analysis
  • Integrated 2 ml vial, 50 positions liquid autosampler with rinse and waste vial*, reloadable during analysis

Instrument control

Windows® based rapid CS cube operating software with LIMS integration and auto sleep and wake-up function for automated and unattended overnight operation. 21 CFR Part 11 functionality available.*

Detector

  • SO2 and CO2 specific infrared detector for sulfur and carbon analysis
  • Electrochemical detector* for chlorine

Maximum furnace temperature

1,200 °C (whereby 1,800 °C is briefly reached at the combustion point when using tin foil)

Required gases

Oxygen or synthetic air

Dimensions

48 x 55 x 55 cm (W x D x H)

* optionally available

Accessories

Electronic balance

Balance and elemental analyzer form a system. We offer analytical balances from the leading manufacturers with our instruments. Please ask us for further information.

Capsule sealing press

Tool for the exact dosing and gas-tight sealing of tin or silver capsules, for liquid and sensitive samples.

Sample former and pressing tools

For simplified sample preparation, we offer a manual tool for compressing samples in tinfoil or cups, and a mechanical press for the preparation of pellets with paper wrapping.

Coal standards

We offer a variety of coal standards with concentrations from < 0.5 % S up to 2.5 – 3.5 % S.

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.

Nutzerfreundliche Wartung: Komfortabel & werkzeuglos

  • Wartung in Sekundenschnelle durch übersichtlich angeordnete, leicht zugängliche Systemkomponenten und ein werkzeugloses Klemmverbindungssystem.
  • Die automatische Ascheentfernung sowie die herausragende Robustheit und Langlebigkeit des Gerätes reduzieren Wartungs- und Reparaturaufwände.
  • Das werkzeuglose Klemmverbindungssystem sorgt jederzeit für ein dichtes, zuverlässiges Gerät ohne Leckage.
