Carbon / Sulfur Analyzer CS-2000

Carbon / Sulfur Analyzer CS-2000

Eltra | Chemical Identification

ELTRA's CS-2000 is the only analyzer on the market for thedetermination of carbon and sulfur in organic as well as inorganic samples. For this purpose, the CS-2000 is equipped with both an induction and a resistance furnace (ELTRA Dual Furnace Technology), covering the full range of carbon and sulfur analysis.

The CS-2000 is available with up to four independent infrared cells, which allow the precise and simultaneous analysis of high and low carbon and/or sulfur concentrations. The sensitivity of the cells can be customized individually by selecting the length of the IR-paths to ensure the optimum measuring range for each application.

Product Advantages
