Total Sulfur
Samples are weighed into a ceramic combustion boat, covered with a vanadium pentoxide or tungsten trioxide accelerator, and transferred into the combustion furnace at 1050ºC. The sample, in the presence of the accelerator and added oxygen, combusts to form SO2 in equilibrium with SO3. This mixture is then conveyed by the nitrogen carrier gas into a second furnace at 825ºC and passed over reduced copper, quantitatively converting all SO3 to SO2, which is subsequently conveyed to the coulometric cell of the detector. There, the resulting sulfur dioxide and/or hydrogen sulfide is automatically measured using absolute coulometric titration.
Data Handling
Names, weights, volumes or areas of up to 50 samples can be entered, to be used by the CM5017S in calculating the final result. Analytical progress is digitally displayed in user-selectable units. A detailed report is printed while each sample is running that includes the final result. The results can also be stored on USB Flash Drive for further data handling.
