Elemental analysis for a better environment Elementar holds the world’s longest tradition in the analysis of the “organic” elements CHNS and O. Today we are all aiming for a cleaner environment which requires more and more the analysis of sulfur and carbon, e.g. in coals, soils and organic samples. Therefore with our special experience a dedicated C/S analyzer has been developed which combines the highest analytical performance with high automatic sample throughput. The concept is straight. Samples are wrapped and automatically fed to a 1200 °C catalytic combustion in pure oxygen. Contained sulfur is converted to SO2 which is measured by means of an NDIR-detector. Carbon compounds are oxidized to CO 2 which is again measured via IR detection. From IR-signal and sample weight the computer calculates the sulfur concentration Automatic analysis for solids and liquids The rapid CS cube has an integrated autosampler which automatically feeds up to 60 or even 120 samples. Solids are wrapped in tin foil or paper and liquids sealed in tin capsules. Full sulfur recovery Combustion takes place in a quartz tube which has advantages compared to ceramics for lower S-concentrations. A permanent temperature near 1200°C and temporarily near 1800°C results in 100 % conversion of S into SO2 even in case of BaSO 4. Large range special NDIR detector The NDIR detector utilizes a gas absorption chamber instead of the more typical solid detector. This results in reduction of noise and an interference free detection. Detection of up to 20 mg absolute sulfur or 40 mg absolute carbon, with a single absorption cell and one detector range is achieved. Closed system for high analytical sensitivity The entire analytical operation takes place in a closed system with no inuence from the ambient atmosphere. This also serves for the highest sensitivity of less than 1 ppm S or C.
