Enantioseparation of Tartaric and Malic Acids in Wines by Ligand Exchange Capillary Electrophoresis Using Uncoated Fused Silica Capillary

Simultaneous CE enantioseparation of tartaric and malic acids using bare fused silica capillary was demonstrated. The combination of dual central metal ion– d -quinic acid system with hexadecyltrimethylammonium based dynamic coating was examined. The background electrolyte contained 100 mM d -quinic...

Summary:Simultaneous CE enantioseparation of tartaric and malic acids using bare fused silica capillary was demonstrated. The combination of dual central metal ion– d -quinic acid system with hexadecyltrimethylammonium based dynamic coating was examined. The background electrolyte contained 100 mM d -quinic acid, 10 mM Cu(II), 0.5 mM Al(III) and 0.5 mM hexadecyltrimethylammonium hydroxide (pH 5.0). The running conditions were −25 kV at 20 °C with direct photometric detection at 250 nm. The analysis time was less than 8 min. Chiral separation of dl -tartaric and dl -malic acids in wines was demonstrated.
