|abstract: ||The simultaneous separation and determination of organic acids in several samples of white and red Port wines was performed by capillary zone electrophoresis using indirectUVdetection with 2,6-pyridinedicarboxylic acid as a background electrolyte buffer. Operational parameters
like migration time, temperature, voltage and capillary length were optimized. Sixteen samples of red wine and four samples of white wine were used to analyze for tartaric, malic, lactic, succinic and acetic acids using glyoxylic acid as the internal standard. The method is rapid, sensitive
and quantitative, and time-consuming sample preparation, such as solid-phase extraction or liquid–liquid extraction procedure, is not required|
