Attain the optimal combination of chromatographic speed and resolution using the new Thermo Scientific™ Dionex™ IonPac™ AS18-Fast-4µm anion-exchange column. This high-capacity, high-efficiency column provides excellent resolution of inorganic anions in diverse sample matrices. This is the hydroxide-selective column of choice for fastest compliance monitoring of inorganic anions in drinking water and wastewater samples in accordance with U.S. EPA Methods 300.0 (A) and 300.1. Compared to the Thermo Scientific™ Dionex™ IonPac™ AS18-Fast column, the new Dionex IonPac AS18-Fast-4µm anion-exchange column uses smaller resin particles for more efficient peaks resulting in faster run times, more accurate peak integration, and more reliable results.
Through the use of smaller resin particles and a shorter column format, this column offers the highest peak efficiency and best resolution of common inorganic anions for fast analysis of environmental waters.Analysis of Common Inorganic Anions and Low Molecular Weight Organic Acids in Diverse Matrices
Higher resolution is achieved through the use of smaller resin particles, which can produce a column backpressure over 3000 psi. When operating the Dionex IonPac AS18-Fast-4µm capillary column at the standard flow rate of 10µL/min, an IC system capable of operating up to 3000 psi is sufficient. However, to take advantage of the fast runs, using elevated flow rates, a high-pressure capillary IC system, such as the Thermo Scientific™ Dionex™ ICS-5000+ HPIC or the Thermo Scientific™ Dionex™ ICS-4000 HPIC is required. The Dionex ICS-5000+ HPIC system is required for standard operation of the Dionex IonPac AS18-Fast-4µm microbore and standard bore columns.Use the Format That Fits Your Lab
Shorter 150mm AS18-Fast-4µm columns facilitate faster runs while the smaller particle size maintains a higher resolution separation and are available in 3 formats with guard columns:
Capillary columns provide significantly reduced operating and waste disposal costs through eluent conservation. Packed with the same material, the Dionex IonPac AS18-Fast-4µm capillary columns provide the same performance as the standard bore and microbore counterparts. Operating costs are reduced because the capillary system operates at only 1% of the eluent flow rate of the standard bore system. Capillary columns are used with the Thermo Scientific™ Dionex™ ICS-4000 and ICS-5000+ Capillary systems.Need Higher Resolution or Faster Separations?
