Peak identification in micellar electrokinetic capillary chromatography

, 2002
Relative mobility was taken as a tool to investigate the peak identification in micellar electrokinetic capillary chromatography (MEKC). The precision (average RSD) of relative mobility was 1.5%, which was, much better than the peak identification with ...

A Novel Micellar Electrokinetic Chromatographic Method for Separation of Metal-DDTC Complexes

The Scientific World Journal, 2012
Micellar electrokinetic chromatography (MEKC) was examined for the separation and determination of Mo(VI), Cr(VI), Ni(II), Pd(II), and Co(III) as diethyl dithiocarbamate (DDTC) chelates. The separation was achieved from fused silica capillary (52 cm × 75
