title: Ligand-exchange ion chromatographic determination of malic acid enantiomers in apple juice with photometric detection.
abstract: An ion chromatographic separation with photometric detection using a chiral copper(II) complex as the eluent has been developed for the resolution of enantiomers of malic acid in commercially available apple juices. The results obtained by this method were in good agreement with those by an enzymatic method with separation by high-performance liquid chromatography.
