In the example shown here we seek to provide an alternative to HILIC methods by using a novel multi-mode column called the Scherzo SS-C18. This stationary phase has both reversed phase (C18) and polar components with the addition of a high density of strong anion and cation exchange ligands. This strategy for increasing polar retention is much more predictable run to run and does not require lengthy column pre-treatments.
