DEVICE AND METHOD FOR ISOLATION, CONCENTRATION AND/OR IDENTIFICATION OF COMPOUNDS

摘要

The invention relates to device and a method for isolating, concentrating and/or identifying at least one analyte by retaining the at least one analyte by a material comprising at least one polymeric material. The device may be a vial which comprises a supporting means supporting a retaining material made of a polymeric material optionally further including a non-polymeric material. The retaining material allows for a selective reversible retention of analyte(s) during solvent evaporation and subsequent elution from the retaining material into a well known volume of solvent. The device and method is especially useful within laboratory work or experiments, e.g. where concentrations of analytes are to be determined. Especially the location and geometry of the retaining material is suitable to retain the analyte(s) during the evaporative removal of the solvent.
