IonPac AS4A-SC ColumnDetailed description of

  • 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.

Separation of the common inorganic anions can be achieved in less than 10 min using an isocratic carbonate/bicarbonate eluent. For simplified operation, use the AS4A-SC Eluent Concentrate and the Combined Seven Anion Standard. The Anion Self-Regenerating Suppressor (ASRS® 300) is recommended for use with the AS4A-SC column.
