<p>System, apparatus and method for efficiently and effectively isolating analytes from a liquid sample by solid phase extraction comprises a workstation platform (20) with a plurality of suction providing stations (12) for receiving either or both a detachably mounted collection chamber (51) housing a removable collection vessel (52) and membrane holder (32) with removable, screen supported disc membrane (42), the holder having an inlet opening (33) for receiving a liquid and a passageway through the screen supported disc membrane to an exit port (39) for flow and collection, at the appropriate time, of analytes, extraction solvent, or liquid sample. The membrane holder (32) is adapted to be releasably mounted into either the suction stations (12) or the collection chamber (51). The removable collection vessel (52) in the collection chamber (51) enables prompt, timely, safe and effective removal of solvent, analyte or liquid from the system. The workstation platform (20) is preferably rotatable for ease of access to the plurality of suction providing stations (12).</p> |
