“…18 was larger than the coefficient (r 2 = 0.7949) obtained from the correlation between log k and log P values in Fig. 19 [20]. The log P is the logarithm of octanol-water partition coefficient that is usually applied to evaluate the polarity or hydrophobicity of drugs and industrial chemicals.…”

“…If an amine (NH 2 ) column is applied, only the anion (COO -) group can provide an extra ion-exchange retention power on the column. When multiple polar protic functional groups such as -OH, -NH (1l2) and -SH contribute to analyte polarity, hydrogen-bonding retention mechanism will exhibit its strength in most HILIC columns [19,20] and this strong hydrogen bond capability can be weakened by switching ACN to methanol in the mobile phase [21]. If greater attention is paid to classification of polar ingredients we need to analyze, this multimodal retention mechanism will benefit our analysts for method development design, especially in column and mobile phase selections.…”

“…HILIC-ESI-MS was also used to investigate the retention behavior of oligomeric proanthocyanidins [106]. The analysis was successfully performed on an amide column without the addition of buffer.…”

“…The poor separation between each oligomer peak suggests that PACE is quite inhomogeneous including different structures showing a high complexity in its PA subunits and the linkages between them (Yanagida et al, 2007;Valls, Millán, Pilar Martí, Borràs, & Arola, 2009). Besides linear PA also large, branched molecules can be present.…”
