Web12 apr. 2024 · Semi-volatile organic compounds (SVOCs) are defined as compounds with boiling points ranging from 240─260 °C to 380─400 °C with polar compounds in the high ends of the intervals (Clausen and Kofoed-Sørensen 2009).Another definition demonstrates SVOCs as compounds with saturation vapor pressures ranging from 10 −2 kPa (10 −1 … WebThere are two common methods for the determination of PAHs in environmental samples. The first is high performance liquid chromatography (HPLC) using EPA methods 610 or 8310. In this method, a combination of UV and fluorescence detection is used to determine 16 common PAHs. This method can be somewhat problematic due to matrix interferences. galvanised iron sheets
