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.

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.
