Primesep 100 separates the monovalent cations, lithium, potassium, and sodium, and the divalent cations, zinc, manganese, and calcium. The cations are resolved by cation exchange. The mobile phase mixture of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) is evaporative light scattering detection (ELSD) compatible.

Neutral sugar, monovalent and divalent cations were separated in HILIC/cation-exchange mode on a Primesep N mixed-mode column. Mobile phase is compatible with LC/MS and method can be used for analysis polar molecules in HILIC, cation-exchange or anion-exclusion modes.
