Ideal for separation of large molecules that carry localized charges, such as surfactants; compatible with acids, bases, and solvents from pH 0 to 14; and can also be used for traditional polymeric reversed-phase applications.

Unique silica-based reversed-phase columns designed for Mobile-Phase Ion Chromatography (MPIC) and compatibility with suppressed conductivity detectors; used to separate moderatelto strong hydrophobic organic ions (such as ionic surfactants, quaternary amines and sulfonic acids), or the separation of multiple-charge ions.

Smaller-pore, solvent-compatible, mixed-mode columns for optimizing separations of hydrophobic and halogenated anions; stable over the entire pH range of 1-14; and particularly well suited for the analysis of larger organic acids, including alkylbenzene sulfonates, aromatic acids, barbiturates, polyphosphates, inositol phosphates, thiocyanate, thiosulfate, and iodate.

Macroporous, solvent-compatible, mixed-mode column for separation of anionic and neutral species in a single run; ideal for analysis of alcohols, alkanolamines, antihistamines, anti-inflammatory agents, aromatic acids, inorganic acids, peptides, purines and pyrimidines, sulfonamides, sulfonated anionic surfactants, and water-soluble vitamins.

Polymer-based, solvent-compatible columns for separating low-molecular weight hydrophobic cations.

Macroporous, solvent-compatible, mixed-mode columns to separate cationic and neutral species in a single run; should always be run with at least 1% organic solvent in the mobile phase.
