摘要
The present invention relates to a method and apparatus for use in performing sample preparation of a liquid sample using solid phase microextraction comprising the steps of drawing a liquid sample comprising analytes into a syringe having a syringe barrel provided with a solid phase material, passing the liquid sample through the solid phase material such that the analytes are adsorbed to the solid phase material; and eluting the analytes with a liquid solvent directly into the injector of an anlysing instrument. The apparatus for performing sample preparation of a liquid sample using solid phase microextraction comprises a syringe having a syringe barrel with a plunger slidable within the barrel and a hollow needle extending from the barrel. The liquid sample is drawn through the needle into the barrel wherein a solid phase material is provided in the syringe barrel to be contacted by the liquid sample drawn into the syringe.
