Introducing an Experimental Design Approach for Efficient Optimization of Chiral Derivatization Conditions for D- and L-Glyceric Acids.

A sensitive analytical method was developed for individual analyses of D- and L-glyceric acids by chiral derivatization - liquid chromatography-tandem mass spectrometry. To elucidate rapid and efficient optimization for derivatization we newly introduced a concept of design of experiments (DOE). The optimization of major 5 factors in the derivatization could be predicted with only 28 measurements. By applying DOE to optimization, the yields of desired derivatives increased five-fold against before optimization.
