For the safe, precise and reliable elemental analysis of carbon (C) and sulfur (S) in predominantly organic matrices such as soils, waste, wood, oil, coal and coke, ELTRA offers the combustion analyzer ELEMENTRAC CS-r with IR detection.

The CS-r with up to 4 infrared cells is designed for carbon and sulfur measurement over a very wide concentration range. It uses a horizontal resistance furnace with ceramic tube, which operates in a range from 600 °C to 1550 °C.

The CS-r elemental analyzer meets or exceeds the requirements of all common ASTM, DIN, EN or ISO standards for elemental analysis.

Volumes of 50 mg to 500 mg are typical for elemental analysis of carbon and sulfur. The sample is directly applied to a carrier (ceramic or Inconel boat) and analyzed without addition of accelerators.

The sample is placed in front of the furnace opening and the measurement is started in the software. Subsequently, the shutter opens, and the material can be introduced into the hot furnace. At the same time, the ELEMENTS software continuously records measured values during combustion. Closing the furnace during the measurement is optional and can improve reproducibility.

60 to 240 seconds after the analysis has started, the measured carbon and sulfur concentrations are available for export as a report or via LIMS. Depending on the selected configuration, carbon and sulfur values are available for the individual sample.

Analizator węgla / siarki ELEMENTRAC CS-r Solutions & Options in Detail

The ELEMENTRAC CS-r analyzer comes with various solutions for reliable and precise carbon and sulfur analysis.

Included: Two Anhydrone Columns

For reliable carbon and sulfur analysis, the combustion gases must be freed from water vapor prior to IR detection. The CS-r elemental analyzer is equipped with two drying columns filled with magnesium perchlorate to reliably prevent absorption effects in large sample volumes. In the case of TOC analysis, a chemical tube can also be used as a halogen trap to reliably absorb acid residues and halogens.

Included: Low blank sample port

The ELEMENTRAC CS-r and CHS-r analyzer series ensures safe and precise elemental analysis even of samples with low carbon content in the resistance furnace. Due to the optimized geometry of the sample port with reduced diameter, as well as an oxygen purge at the sample inlet, the CO2 blank value of the atmosphere during sample introduction is drastically reduced, thus enabling reliable carbon analysis in the low measuring range.

Option: Second Furnace (ELTRA Dual Furnace Concept)

The CS-r elemental analyzer can be connected in any configuration to an additional furnace without detectors. This principle, known from the ELEMENTRAC CS-d, allows fast fractionated analysis by applying different temperatures and provides safety for high sample throughput.

Option: Monitor Holder

To make the most of available laboratory space, the ELEMENTRAC CS-r analyzer offers various operating options:
  • External monitor and keyboard
  • Monitor holder, wireless keyboard
  • Operation via touchscreen

Option: TIC Module

Depending on the sample, carbon can also be present in the two different fractions TOC (Total Organic Carbon) or TIC (Total Inorganic Carbon). The CS-r elemental analyzer can be combined with ELTRA's TIC module to determine the TIC content via acidification. This combination enables reliable, direct TIC analysis in soils, building materials and other products in compliance with DIN EN 15936.

Analizator węgla / siarki ELEMENTRAC CS-r Zasada działania

In the elemental analyzer CS-r the sample is burnt in an oxygen atmosphere at temperatures up to 1,550 °C. The furnace temperature can be freely selected in steps of 1 °C. The combustion gasses (CO2, H2O, SO2) coming from the furnace and pass through a dust filter. After the water vapor is chemically absorbed, the dried CO2 and SO2 gas is detected in the additional infrared cells. Depending on the configuration, it is possible to combine up to four (for C, S analyzers) infrared cells with different sensitivities.
