Separation of plant growth regulators by capillary electrophoresis

Capillary electrophoresis (CE) was used for the separation of nine plant growth regulators. Cyclodextrins and cholic acid were used as modifiers in the electrophoretic buffer to enhance selectivity. Satisfactory separation was obtained using a phosphate-borate buffer containing α-, β- and γ-cyclodex...

Description
Summary:Capillary electrophoresis (CE) was used for the separation of nine plant growth regulators. Cyclodextrins and cholic acid were used as modifiers in the electrophoretic buffer to enhance selectivity. Satisfactory separation was obtained using a phosphate-borate buffer containing α-, β- and γ-cyclodextrin. The effects of pH and applied voltage on the migration behaviour in this system were studied.
