Determination of Total Carbon and Sulfur in Forty-Two Geochemical Reference Samples By Combustion and Infrared Spectrometry

Total carbon and sulfur were determined on a variety of geochemical reference samples such as rocks, sediments, minerals and ores by a method of infrared absorption following combustion in a high-frequency induction furnace. The sample was burned with an accelerator of iron powder and tungsten chips, and the carbon and sulfur dioxide in the evolved gases have been determined directly by a simultaneous infrared analyzer. The agreement between present results and other data is generally good.
