<p>The present invention is a disposable apparatus for the rapid, low-volume solid phase extraction of analytes from a variety of sources. The apparatus of the present invention is configured as a pipette tip (10) and contains a loosely confined stationary phase (18). The mobility of the stationary phase particles enables rapid mixing and equilibration with a sample solution during agitation. The analyte may thereby be extracted in less time with less solvent, removing the need for a separate concentration step.</p> |
