Total Sulfite, SO2/H2S
Samples are initially weighed into disposable Teflon® cups and loaded into a 45 position sample carousel. As the carousel rotates, each sample drops from the carousel into a small chamber where it is purged with a SO2-free carrier gas to eliminate atmospheric interferents. Once purged, the sample moves into the acidification chamber where it is oxidized. A second stream of SO2-free carrier gas transports the products of this reaction through a series of post-scrubbers (to remove potential interferences) and ultimately into the reaction cell of a CM5017S SO2 Analyzer where sulfites evolved as SO2 are 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. Upon completion of a series of samples, a one page report will print, summarizing the analysis of all 50 samples. The results can also be stored to diskette for further data handling.
