The IonPac® AS4A-SC 2 mm and 4 mm anion-exchange columns are designed for the fast analysis of inorganic anions in environmental waters. The AS4A-SC was introduced in 1984 and has been the preferred column for inorganic anion analysis for many years. It is the specified column in US EPA Method 300.0 (A).

  • Resolves inorganic anions in 8 min using an isocratic carbonate/bicarbonate eluent.
  • Sodium tetraborate gradient optimizes difficult separations.
  • Meets or exceeds US EPA Method 300.0 (A) performance requirements.
  • Provides excellent performance for fast analysis of inorganic anions.

The IonPac AS4A-SC (solvent-compatible) is a low-capacity carbonate eluent anion-exchange column for the fast, isocratic separation of inorganic anions such as nitrate or sulfate, using a carbonate/bicarbonate eluent coupled with suppressed conductivity detection. Inorganic anions are easily determined in any liquid, including water, foods, and other diverse sample matrices.
