FUNCTION PRINCIPLE
Operation CHS-580A
In the CHS-580A the samples are weighed into crucibles. Then a gripper places the samples from the Autoloader on the pedestal. The samples are loaded consecutively into the furnace for combustion. The average analysis time is 60 to 180 seconds. 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 analyzers require minimum maintenance. The particle filters and chemicals which need to be maintained are easily accessible.
Measuring Principle CHS-580A
In the CHS-580A analyzer the sample is burnt in an oxygen atmosphere at temperatures of 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 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 four infrared cells with different sensitivities.
