Rapid CS Cube

High performance carbon and sulfur analysis

Elementar’s rapid CS cube is a carbon and sulfur analyzer that offers industry-leading performance in carbon and sulfur analysis, combining exceptional analytical performance with operational efficiency and automated sample throughput.

Fast and sensitive IR-enabled SO2/CO2 determination capabilities make the system ideal for sulfur and carbon analysis, offering precise sensitivity and easy of use when working with coal, soil or waste samples.

These innovations enable the carbon and sulfur analyzer to deliver a highly optimized performance, meeting the specific needs of laboratories with impressive efficiency and speed.

Specifications:

Quantitative high-temperature decomposition

The rapid CS cube operates at a constant temperature of around 1,200 °C, reaching 1,800 °C during combustion. In pure oxygen, the sulfur fully converts into SO2 with 100% recovery, even in the case of BaSO4. Carbon converts to CO2 and detected by a true non-dispersive IR photometer.

Large weighing range

The instrument’s range encompasses micro (less than 1 mg) and macro (1 g) applications, depending on the sample type.

Large dynamic concentration range

The measuring range spans 0-100% for both sulfur and carbon. Sulfur can be measured up to or 20 mg absolute, and carbon up to 40 mg absolute, all with a single IR detector and sensitivity range. It can even detect concentrations below 1 ppm or 0.2 µg S.

Automated analysis

The integrated sample magazine holds up to 60 large samples for fully automated, unattended analysis, even overnight. For solid materials like coal, up to 120 samples can be loaded, while liquid samples can be sealed in tin capsules and placed in the autosampler.

In accordance with international standards

ASTM 4239 (S in coal and coke), ISO 15178 (S in soil), EN 15936 (TOC in solids), etc…

One detector for the entire measuring range

For excellent analytical sensitivity and minimized calibration effort

Low maintenance

Through clean combustion, avoiding dust formation and contamination of the analyzer
