RP similarity

RP retains molecules according to their hydrophobicity, some correlation clearly exists between these two LC modes. Apparently, the peptide size loosely correlates with hydrophobicity in general, the bigger peptides elute earlier in SEC and later in RP. Similarly, HILIC and RP are also likely to exhibit some selectivity correlation, as their retention mechanism is related to hydrophilicity (HILIC) or lack of hydrophilicity (RP).
