的詳細(xì)介紹
IonPac AS4A-SC Carbonate Eluent Anion-Exchange Column
For the Fast Isocratic Separation of Inorganic Anions in Drinking Water and Wastewater
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.
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.
Note: The AS22 is the newest carbonate eluent column recommended for fast analysis of inorganic anions.
