Chiral quantification of D-, L-, and meso-tartaric acid mixtures using a mass spectrometric kinetic method.

Accurate quantification of the optical isomers in a ternary mixture of D-, L-, and meso-tartaric acids is achieved using electrospray ionization tandem mass spectrometry for in-situ metal complex formation and a three-point calibration method to quantify the dissociation kinetics.
