The XB-C8 phase is less retentive than XB-C18 phase, more useful for compounds that are too strongly retained on C18 phase, and for LC/MS applications, where the long retention is not required. When separating neutral or other highly retained compounds, using XB-C8 can save analytical time. However, when separating polar compounds, XB-C8 column provides alternative selectivity than XB-C18 column.
