Overlaid HPLC-PDA chromatograms demonstrating the chromatographic separation of UV-irradiated samples of (a) 1,3-diCQA, (b) 1,5-diCQA, (c) 3,4-diCQA, (d) 3,5-diCQA, and (e) 4,5-diCQA analyzed on either a bi-phenyl or C₁₈ column matrix. The figure shows differences and similarities in the elution profiles, dependent on either the bi-phenyl or C₁₈ column matrix. T represents the di-trans-isomer, M ^∗ represents the first eluting mono-cis-isomer, M ^# represents the second eluting mono-cis-isomer, and C represents the di-cis-isomer.
