Analyses of enantiomeric purities of L- and D-isomers of 18F-FBPA (c) and 11C-CMT (d) used in PET measurements. The enantiomeric purity of each compound was analyzed on a CROWNPAK CR(+) column using an elution solution of perchloric acid (pH 2.0) at a flow rate of 2 mL/min. The identification of each compound was conducted by comparing the elution time to each corresponding authentic standard compound of L- and D-FBPA (a) and L- and D-CMT (b)
