HPLC ELSD Method for Separation of Metal Ions on Primesep 100 Column

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.
