Rapid and quantitative determinations of the enantiomeric compositions of pantothenic acid solutions were carried out by using electrospray ionization tandem mass spectrometry and applying the kinetic method to perform the data analysis. Deviations of ca. 1% between the actual and experimental enantiomeric compositions were observed.
