The Dionex IonPac AS16 Analytical Column 4x250 mm P/N 055376 is a high capacity, hydroxide selective anion exchange column designed for the isocratic separation of polarizable anions including iodide, thiocyanate, thiosulfate, and perchlorate in a variety of sample matrices.
The Dionex IonPac AS16 Analytical Column 4x250 mm P/N 055376 has a capacity of approximately 170 μeq/column which allows large loop injections without column overloading. Under isocratic conditions, the polarizable anions can easily be separated in approximately 20 minutes. Trace concentrations of perchlorate in drinking water, surface water and ground water matrices can easily be determined using a large loop injection. With 50 mM sodium hydroxide eluent, perchlorate can be determined in approximately 10 minutes. The AG16 guard column is packed with a microporous resin with a lower capacity. The microporous resin ensures optimum long term performance of the guard column.
