Separation of Silver and Potassium Ions on Newcrom AH Column
View on

Silver and potassium ions can be separated on a mixed-mode Newcrom AH column with a simple isocratic mobile phase consisting of water, acetonitrile (ACN) and methanesulfonic acid.  By adjusting the amount of acetonitrile used in the mobile phase, the elution order of the ions can be reversed.  The ions can be detected using a conductivity detector.

Application Column

Newcrom AH

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.
