Application of pH-responsive poly(2-dimethyl-aminoethylmethacrylate)-block-poly(acrylic acid) coatings for the open-tubular capillary electrochromatographic analysis of acidic and basic compounds
A new type of stimuli-responsive polymeric coating for OT-CEC has been prepared.
•
The Y-shaped copolymer enables EOF magnitude and direction to be easily adjusted.
•
Acidic and basic compounds analysed under different pH and ionic strength conditions.
•
EOF-driven separations achieved with organic solvent free buffer electrolytes.
•
Excellent repeatability over many cycles of use in the OTC-CEC mode achieved.
