Function Principle
Operation CHS-580
After weighing the sample in a ceramic boat, the weight is transferred from the interfaced balance to the PC. If required, sample weights can also be entered manually. Then the ceramic boat is introduced into the furnace for combustion. The average analysis time is 60 to 180 seconds. The detector signals and instrument parameters are displayed during analysis. Evaluation of the signals and display of the results are done automatically; the data can be transferred to a laboratory information management system (LIMS). The CS-580 requires minimum maintenance. The particle filters and chemicals which need to be maintained are easily accessible.

Measuring Principle CHS-580
In the CHS-580 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 first pass through a dust filter and then into the heated H2O infrared cell. 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 three infrared cells with different sensitivities.
