Organic matter of various composition is present in soils and sediments ranging from simple compounds to the very complex proteins, etc. Within the pollutant analysis in soils and sediments the total organic carbon (TOC) content is determined. In addition to this form carbon may be present as elemental or inorganic ones. TOS identification and quantitation methods may be qualitative or quantitative with prior sample preparation. It is recommended catalytic combustion of samples at high temperatures with Pt catalyst and IR detection of evolved CO2.
