Analyze inorganic cations and amines using the Thermo Scientific™ Dionex™ IonPac™ CS20 ion chromatography (IC) columns.

High-capacity ion-exchange column with 4 μm resin for highest resolution of cations and polar amines in complex samples. Enables fast, reliable separations and cost-effective operation with HPIC systems.

Separate common inorganic cations, small polar amines and polyvalent amines using Thermo Scientific Dionex IonPac CS19 IC Columns

Separate polar amines with the Thermo Scientific™ Dionex™ IonPac™ CS18 Cation-Exchange Column.

Obtain excellent selectivity and peak shapes for hydrophobic amines in complex matrices without solvent using the Thermo Scientific Dionex IonPac CS17 column.

Resolve ammonium and sodium at ratios up to 10,000:1 with CS16-4μm columns. Faster, high-resolution cation analysis without pretreatment—even in complex matrices.

Resolve sodium and ammonium at ratios up to 20,000:1 with the IonPac CS16 column—ideal for complex matrices and adjacent cation analysis with high efficiency and low eluent use.

Achieve accurate trace-level ethanolamine determination in high-ammonium matrices with the unique selectivity of the Dionex IonPac CS15 carboxylate-functionalized cation-exchange column.

Thermo Scientific Dionex IonPac CS14 IC is moderately low capacity cation-exchange column for analysis of aliphatic amines, aromatic amines, and polyamines using MSA or sulfuric acid eluents.

Separate common cations in as little as four minutes using methanesulfonic acid (MSA) or sulfuric acid eluents with Thermo Scientific Dionex IonPac CS12A Cation-Exchange Columns.
