We recommend that any chromatographer who is analyzing complex peptide mixtures
evaluate both columns. The PS-C18 and XB-C18 columns exhibit contrasting selectivity
due to the differences in surface chemistry, and chromatographers can utilize
these differences to achieve improved resolution between target peptides in different
regions of their peptide map.
