To recognize the conditions of soil contamination by oil, to know the concentration of contaminants in the soil is necessary. Total Petroleum Hydrocarbons (TPH) is commonly used to assess oil contaminated soil. TPH measurement methods in the laboratory usually adopt solvent extraction of the hydrocarbon from the soil prior to gas chromatography (GC) or infrared (IR) analysis. In order to increase the laboratory efficiency and reduce the cost of soil contamination investigations, some screening analysis methods are used. In this study, in order to develop a screening analysis for oil contaminated soil, a method to determine TPH values by measuring CO₂ concentrations of burning gas from soil sample was investigated and established as TPH analyzer.
