          IonPac AS14A Carbonate Eluent Anion-Exchange Columnhe IonPac® AS14A anion-exchange column is a carbonate-based column for fast analysis of the common inorganic anions

          詳細(xì)介紹

          Fast Analysis of the Common Inorganic Anions in Diverse Sample Matrices

          The IonPac® AS14A anion-exchange column is a carbonate-based column for fast analysis of the common inorganic anions in diverse sample matrices. The AS14A meets the performance requirements specified in US EPA Method 300.0 (A).

          • High efficiency and fast analysis (8 minutes)

          • High-capacity applications (13 minute run time)

          • Improved peak shape, efficiency, and pH stability

          • Meets or exceeds US EPA Method 300.0 (A) performance requirements

          Simplified operation with AS14A Eluent Concentrate and Combined Seven Anion Standard

          The AS14A is designed for the separation of inorganic anions, including fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate, using a carbonate/bicarbonate eluent coupled with suppressed conductivity detection. The inorganic anions can easily be determined in drinking water, wastewater, foods and beverages, scrubber solutions, and other diverse sample matrices.

          For simplified operation use the AS14A with AS14A Eluent Concentrate and the Combined Seven Anion Standard. Use the ASRS 300 suppressor with the AS14A column for low-noise operation.

          Note: See also the IonPac AS22, the newest carbonate eluent column recommended for fast analysis of inorganic anions.
