Carbon Determination in Soils and Organic Materials with A High-Frequency Induction Furnace1

Abstract

Abstract

Application of established procedures for determination of carbon (C) in metals yielded about 60 to 90% C recovery from soils and pure organics. Systematic instrument and procedural changes showed that low recovery was due to escape of pyrolysis products or other volatile organic materials. Complete C recovery from dry soils and pure organics was achieved by adaptations employing an internal quartz-enclosed graphite ignitor or an external auxiliary resistance furnace. The procedures also permit analysis of total C in residues from soil extracts or other solutions and for inorganic C and organic C in soils.
