Analyze trace perchlorate and other highly polarizable anions including thiosulfate, iodide, and thiocyanate in a variety of water matrices by ion chromatography (IC) using Thermo Scientific™ Dionex™ IonPac™ AS16-4µm columns. Compared to standard Dionex IonPac AS16 columns, these new Dionex IonPac AS16-4µm columns use smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results. Dionex IonPac AS16-4µm columns are the ideal choice for determining trace perchlorate in drinking water in accordance with U.S. EPA Methods 314.0, 314.1, 314.2, and 332.
Higher resolution is achieved through the use of smaller resin particles, which produce a column backpressure over 3000 psi at the standard flow rates. A high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-5000+ HPIC™ system, Dionex Integrion™ HPIC system, or the Dionex ICS-4000 Integrated Capillary HPIC system is required to operate this column under standard conditions.Reduce operating costs with lower eluent requirements
Capillary Dionex IonPac AS16-4µm columns provide the same performance as the standard bore and microbore Dionex IonPac AS16-4µm columns because they are packed with the same material. Operating costs are reduced because the capillary system operates at only 1% of the eluent flow rate of the standard bore system, requiring less eluent and producing less waste.
