Specification
Carbon / Sulfur Analyzer ELEMENTRAC CS‑r
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.
