Validation of Petroleum Hydrocarbons Determination in Soil by Fourier Transform Infrared Spectroscopy

摘要

The paper presents the validation and the estimation of the measurement uncertainty for the determination of petroleum hydrocarbons in soil by Fourier transform-infrared spectroscopy. For the method validation selectivity, limit of detection and limit of quantification, working range, trueness, precision and recovery were studied and the measurement uncertainty was evaluated based on the bottom-up approach. The method limit of quantification was found to be 30 mg/kg, the working range 30-2500 mg/kg, the recovery 105%, while the measurement uncertainty was found to be 11%.
