摘要
An extraction device for liquid-liquid extraction of at least one analyte from a sample and on-line transfer of the analyte(s) to a gas chromatography extraction unit, a sample inlet, a sample outlet, and an organic liquid inlet, wherein the extraction device also includes a needle to be connected with a gas chromatography apparatus injector for the on-line transfer of the analyte(s) from the membrane-based extraction unit to the gas chromatography apparatus via the needle, an organic liquid being immobilized as a stagnant phase in a volume of less than 20 mul in the membrame-based extraction unit.
