Expressions are formulated for the prediction of solute migration time and resolution as a function applied voltage and buffer concentration in capillary zone electrophoresis. The resolution equation assumes that solute diffusion is the only operative zone-broadening mechanism. A resolution surface

The mechanism of the formation of substituted quinolines from anilines and alpha,beta-unsaturated ketones has been studied by the use of 13C-labeled ketones in cross-over experiments. In the reaction of doubly labeled 13C(2,4) mesityl oxide, a 100% scrambling of the label

Cysteine conjugates, resulting from the addition of cysteine to alpha,beta-unsaturated carbonyl compounds, are important precursors of odorant sulfur compounds in food flavors. The aim of this work was to better understand this chemistry in the light of the unexpected double

Electrophoresis, 22(6), 1112-1118 (2001-05-19)
A fast screening method for the determination of the dissociation constants (pKa) of acidic, basic, and multivalent compounds was developed by using pressure-assisted capillary electrophoresis (PACE). External air pressure was applied to shorten the analysis time. The separation efficiency decreases

The Analyst, 137(20), 4766-4773 (2012-08-25)
Capillary electrophoresis (CE) is not only an effective separation technique, but can also serve as a sample preparation tool for enrichment and purification at sub-microliter sample volumes. Our approach is based on the use of a discontinuous buffer system consisting
