<p>Apparatus, methods and polymers for solid phase extraction by binding an analyte containing a primary amino group The polymer is a reactive polymer, wherein binding of the analyte to the polymer causes fluorescent isoindole complex for-mation. A method of binding comprises use of an SPE carrier, such as an SPE cartridge, loaded with a reactive polymer Binding of an analyte is detected by observing changes in fluorescence after applying the analyte to the polymer Fluorescence can be de -tected using a fluorometer or transilluminator, for example In a preferred embodiment, the reactive polymer is prepared from a monomer mixture comprising acetorutrile and methylamine.</p> |
