IonPac NS1 Reversed-Phase LC Column


Polymeric Reversed-Phase Column Ideal for the Separation of Hydrophobic, Ionizable Compounds

The IonPac? NS1-10μm and NS1-5μm columns are packed with a neutral, macroporous, high-surface-area, ethylvinylbenzene polymer crosslinked with 55% divinylbenzene. This resin makes the NS1 resistant to solvents, acids, and bases, and permits the use of eluent from pH 0 to 14.

  • Ideal for separation of large molecules that carry localized charges, such as surfactants
  • Compatible with acids, bases, and solvent from pH 0 to 14
  • Can also be used for traditional polymeric reversed-phase applications
  • Utilize ion-pair chromatography for difficult separations

The IonPac NS1 column is the column of choice for routine ion-pair chromatography or ion-suppression separations using theAMMS? ICE 300 suppressor. The NS1 is also used with phase ion chromatography (MPIC?), a technique especially suited to large molecules that carry localized charges (e.g., surfactants), as well as other ions that are not amenable to separation by ion-exchange chromatography.

Key Applications

The IonPac NS1 column can be used for the separation of high MW aliphatic carboxylic acids, alkyl and aromatic sulfates and sulfonates, quaternary ammonium ions, water-soluble vitamins, sulfur oxides, metal cyanide complexes, phenols, alkanolamines.
