On-line preconcentration for the determination of aflatoxins in rice samples by micellar electrokinetic capillary chromatography with laser induced fluorescence detection

MEKC coupling with LIF detection has been used for the determination of four aflatoxins (B1, B2, G1 and G2). Separations were performed in an uncoated fused-silica capillary (70 cm×75 μm id, 55 cm effective length), using 20 mM borate buffer with 30 mM SDS (pH … Continue reading

Advances and analytical applications in chemiluminescence coupled to capillary electrophoresis

The present review presents the state of the art of the developments, key strategies and analytical applications of chemiluminescence detection coupled to CE (CE-CL). Different parts considering the most common CL systems have been included, such as the tris(2,2′-bipyridine)ruthenium(II) system, … Continue reading
