Learn how carbon sulfur analyzers work, compare high frequency infrared vs tube furnace types, and explore applications across steel, mining, and cement industries. Carbon and sulfur are among the most consequential elements in metallurgical and materials analysis. The elemental analyzer ELEMENTRAC CS-i measures the carbon and sulfur concentration in predominantly inorganic samples through combustion in an induction furnace and the subsequent analysis of the gaseous combustion products carbon dioxide and sulfur dioxide.
