Ion Analysis

Concise Separations Columns for Ion Analysis

  • Rugged polymeric substrate with full pH stability from 0 to 14
  • Excellent solvent compatibility for flexible IC method development
  • High column efficiency for sharp, well-resolved anion peaks
  • Reliable lot-to-lot and column-to-column reproducibility
  • Strong anion-exchange chemistry ideal for comprehensive anion profiling

Concise Separations ion chromatography (IC) columns are engineered for robust, reproducible ion analysis across a wide range of IC systems. Built on a durable polymeric substrate with exceptional chemical stability, these columns maintain performance over aggressive pH conditions, enabling consistent retention and long operational lifetimes.

Each column is optimized for high-efficiency anion separations using strong anion-exchange functional groups that deliver reliable peak shape, selectivity, and resolution. Their broad solvent compatibility supports diverse eluent systems, allowing analysts to tailor IC conditions for environmental, industrial, and regulatory applications.

Concise Separations IC columns are fully tested for compatibility with Metrohm, Dionex, Hach–Lachat, Alltech, and other major IC platforms. Their selectivities align with widely used industry standards, including methods specified in EPA 300 (Parts A and B) and EPA 300.1, ensuring seamless method transfer and regulatory compliance.

Key Definitions ▸
Ion Chromatography (IC)
A chromatographic technique used to separate and quantify anions and cations using ion-exchange mechanisms. IC is widely applied in environmental monitoring, water quality analysis, and regulatory compliance testing.
Strong Anion Exchange (SAX)
A stationary phase chemistry featuring strongly basic functional groups that retain negatively charged analytes. SAX columns provide high selectivity for inorganic and organic anions across a wide concentration range.
pH Stability (0–14)
The ability of a polymeric column substrate to withstand highly acidic and highly basic eluent conditions without degrading, enabling aggressive cleaning and flexible IC method development.
EPA Method 300 / 300.1
U.S. Environmental Protection Agency methods describing approved ion chromatography procedures for measuring inorganic anions in drinking water and wastewater, ensuring regulatory compliance for public health and safety testing.
Solvent Compatibility
The ability of an IC column to withstand a variety of aqueous eluents and conditioning solvents without compromising performance, enabling broader application flexibility.
