Figure 2-10. Dual comprehensive two-dimensional chromatogram of polyphenolic and flavonoid compounds recorded in subsequent HILIC mode (left, gradient of decreasing acetonitrile concentration) and reversed-phase mode (right, gradient of increasing acetonitrile concentration) on a single monolithic capillary zwitterionic polymethacrylate BIGMA-MEDSA column in the first dimension coupled online with a Kinetex XB-C18, 50 x 3.1 mm I.D., coreeshell column in the second dimension.

Based on the data from Hajek, T., Jandera, P., Stankova´, M., Cesla, P., 2016. J. Chromatogr. A 1446, 91-102.
