Determination of Purgeable Organics in Sediment
The analysis of volatile organic compounds in sediment poses challenging problems. Previous methods have been insensitive to low concentrations of volatiles in sediments. The reasons behind this are twofold. Sediment analysis is usually limited to a 50 gm sample size for ease of sample handling. A liquid extraction of a sediment sample this large would be difficult. The large volumes of solvent required could not be concentrated by any solvent stripping technique without loss of the organics in question. Head space analysis is limited to small volume injections of low concentration resulting in a minimum detectable limit of 25 ppb “EMSL, Cincinnati, Ohio” (1977).
