Abstract
The organic acids quinic, malic, shikimic and citric were separated on a packed reverse phase fused-silica capillary column using 0.01 M K2H PO4/H3PO4 at pH 2.7 as eluent at a flow rate of 2 mu L/min, and determ ined with UV detection. Conventional liquid chromatographic equipment was adapted for such purposes. The organic acids were able to be separ ated with detection limits of 2.4, 2.1, 0.04 acid 2.9 ng, respectively . Application of the proposed method to the quantification of organic acids in apple juice is reported.
