IonPac AS4A-SC 阴离子交换色谱柱
The IonPac AS4A-SC (溶剂兼容) 是一款低容量碳酸盐体系阴离子交换色谱柱，用于快速，等度分离各种水样无机阴离子。
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.
