Application Column
Newcrom A
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.

HPLC ELSD Method for Separation of Metal Ions on Primesep 100 Column
October 4, 2005
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.
