Combustion Analyzers for TOC Analysis of Solid Materials

The TOC (total organic carbon) content is an important parameter to characterize materials like soil, rocks or cement. It can be determined by controlled combustion at a fixed temperature, by application of a temperature ramp or by adding acid. ELTRA offers high-performance combustion analyzers for all these methods.

The CW-800 and CW-800M (Fig.) are suitable for the determination of both TOC and TIC (total inorganic carbon) content in one sample by application of different carrier gases and temperatures. The CW-800M is used for applications with temperature ramps.

Due to their robust construction the combustion analyzers CS‑800, CS-580 and CS-580A are suitable for measuring acidulated samples. They operate with gold cuvettes which replace the costly halogen traps. The use of sample loaders facilitates the handling of larger sample series.
