Abstract
A method for extracting an analyte from a solid sample is described. The sample is sealed in a porous membrane bag, which is sonicated in an organic solvent. An extract of the analyte forms in the bag and diffuses into the organic solvent. The organic solvent containing the extract may then be concentrated and analyzed for an analyte with gas chromatography-mass spectrometry. The method does not the use of a solid sorbent material, and does not require a step of centrifuging or filtering.
