Investigation on Chiral Amino Acids Enantiomeric Excess With Cyclodextrin Inclusion Complex Ions Assisted Differential Ion Mobility Separation Mass Spectrometry

= 0.996) between peak abundance ratios and molar ratios of L-serine and D-serine. This method does not require the use of metal ions, and the single peak shape in ionograms of chiral AA-α-CD complex ions simplifies data interpretation.
