chemical extraction using polypropylene membrane filled with organic solvent and placed into the aqueous sample. Sample preparation method for chromatography based on liquid/liquid extraction procedure where the phases are separated by the membrane. It can be fully automated. Typical applications: extraction of extractable hydrocarbons (EPH), PAHs, phenols, PCBs, pesticides from water or aqueous suspensions. Suitable for analytes to be extracted from extremely dirty matrices. (Source: B. Hauser, M. Schellin, and P.
