In this work, for the first time, capillary zone electrophoresis (CZE) technique combined with microwave-assisted extraction (MAE) was developed for the fast quantification of chlorogenic acid (CA) in tobacco residues. CA in tobacco residue samples were extracted by MAE technique, and then analyzed by CZE. As a new sample preparation method for tobacco residues, the MAE procedure is optimized, validated...
Capillary zone electrophoresis separation with laser-induced fluorescence (LIF) detection for the determination of fluorescein isothiocyanate (FITC) derivatized stimulants (ephedrine, phenylpropanolamine and heptaminol) was demonstrated. A simple electrophoretic buffer system composed of 30mM triethylamine was selected and high voltage of 16kV was applied for the capillary electrophoresis separations...
