Dionex™ IonPac™ NG1-10μm Guard Column (4 x 35 mm)

Achieve high-efficiency separations of hydrophobic, ionizable compounds with Thermo Scientific™ Dionex™ IonPac™ NS1 10μm Analytical & Guard Columns. The columns of choice for ion-pair or ion-suppression chromatography, these polymer-based, reversed-phase columns provide excellent resolution and peak shape. Packing is a neutral, macroporous, high surface area, ethylvinylbenzene polymer cross linked with 55% divinylbenzene, making IonPac NS1 columns resistant to solvents, acids and bases while permitting the use of eluent from pH 0 to 14.

Polymer-Based Columns for Efficient Reversed-Phase Separations

• Ideal for separation of large molecules that carry localized charges, such as surfactants
• Can be used for traditional polymeric reversed-phase applications
• Use with ion-pair chromatography for difficult separations
• Available in 5 and 10μm particle sizes

Key Applications
Use IonPac NS1 columns for reliable separations of various compounds: High molecular weight aliphatic, carboxylic acids; Alkyl and aromatic sulfates and sulfonates; Quaternary ammonium ions; Water-soluble vitamins; Sulfur oxides; Metal cyanide complexes; Phenols
