            (7) Solid Phase Reagents

            Compared with liquid-phase derivatizations, the solid-phase derivatization approach has become
            increasingly attractive due to some unique features, such as good selectivity and ease of operation.
            Some polymeric reagents for the solidphase derivatization have been proposed (Fig. 3.17) [70-72].
