Webphases, including SEC, HILIC, RP at pH 2.6 and pH 10 and SCX. HILIC was shown to have a separation power superior to both SCX and SEC [11]. The orthogonality— i.e., how different the separation mechanisms are—of the stationary phases was determined by plotting the peptide retention times of two dimensions against each other (see Fig. 2).
