Thermo Fisher, 056897, Dionex™ IonPac™ AS14A IC Columns

Length (Metric): 50 mm
Diameter (Metric): 4 mm
Column Type: Guard Column
Unit Size: Each 1
Fast Separation of Inorganic Anions in Diverse Matrices
• Compliance monitoring of common anions in drinking water as specified in U.S. EPA Method 300.0 (A)
• Separation of common inorganic anions in 8 min (3 x 150mm format) or 13 min (4 x 250mm format) in diverse sample matrices
• Superior retention and quantification of fluoride
• Compatible with sodium or potassium hydroxide gradient to optimize difficult separations
• Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components. Multiple Formats Available for Application Flexibility
• 4x250mm, 3x150mm analytical columns
• 4x50mm, 3x30mm guard columns
• Longer 250mm columns facilitate higher resolution separations of more complex sample matrices
• Shorter 150mm columns produce faster runs of relatively clean matrices
• Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs Note: Use with the Dionex IonPac AS14 Eluent Concentrate and the Combined Seven Anion Standard for simple, accurate eluent preparation.
