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.
Carbon / Sulfur Analyzer ELEMENTRAC CS-r
Fast, simultaneous measurement of carbon and sulfur
High sample weight possible
Optimized (low blank) sample port
IR path made of solid gold for extended lifetime
Wide measuring range from 20 ppm to 100%
Operation and Analysis Process
The ELEMENTRAC CS-r analyzer determines the elements carbon and sulfur by combustion of the sample in an oxygen stream and subsequent measurement of the combustion gases CO2, SO2 and H2O in selective infrared measuring cells. A high sample weight of up to 500 mg ensures excellent reproducibility of the elemental analysis results, even for heterogeneous samples.
The high combustion temperatures and electronic monitoring of the oxygen flow allow complete oxidation of the sample and help to avoid too low results even with challenging materials like cement. Regardless of the selected configuration (carbon – sulfur - carbon and sulfur), operation is identical in all analyzer versions.
