    摘要: The invention relates to a method, particularly suitable for the extraction and enrichment of a volatile component from a liquid, solid or gaseous sample for subsequent introduction into an analytical device, for example, a gas chromatograph. The sample is flushed through a packing of extraction material for extraction of the analytes of interest. A suitable device comprises a syringe with a hollow needle. A chamber is provided between the needle and syringe, in which the extraction material is arranged.
