 note = {A highly sensitive and selective capillary zone electrophoresis with laser-induced fluorescent detection (CZE-LIF) for Al^<3+> and Ga^<3+> was developed using a calcein 4’,5’-isomer as a pre-capillary complexing agent. Direct fluorescent detection without an agent added to the carrier buffer provided the notable detection limits of 3.9 × 10^<-10> and 4.6 × 10^<-10> mol dm^<-3> for Al and Ga, respectively. By applying a river water sample successfully to this system, its potential for practical applications was ascertained. A comparison of three aromatic polyaminocarboxylate ligands related to the coordination structure and the distance between the fluorophore and the chelating moiety, revealed some interesting factors regarding their selectivity, application/pdf},
