Abstract
Measured sample quantities of sulfureous matter are introduced into a sealed chamber where the samples are pyrolyzed to form sulfur dioxide and sulfur trioxide gases and to oxidize organic substances to form carbon dioxide gas. The gases are then passed through a free sulfur-absorbing packing and into a scrubbing zone wherein transition metal amine complex is used to remove sulfureous compounds without reaction with the carbon dioxide gas. The scrubbed gases are then analyzed to determine the carbon dioxide content thereof.
