Description

Length (Metric): 50 mm
Diameter (Metric): 4 mm
Column Type: Guard Column
Unit Size: Each 1
Analysis of Inorganic Anions and Oxyhalides in Environmental Matrices
• Compliance monitoring of common anions and oxyhalides in drinking water as specified in U.S. EPA Methods 300.1 and 317.0
• Simple, isocratic separation of trace bromate (5μg/L) in ozonated drinking water matrices
• Superior results in difficult applications, such as trace nitrite in complex sample matrices
• Similar selectivity to the Dionex IonPac AS9-SC column, but with higher capacity for improved separation of trace bromate in drinking water
• Solvent compatibility for easy column cleanup after the analysis of samples with hydrophobic componentsMultiple Formats Available for Application Flexibility
• 4 x 250 mm, 2 x 250 mm analytical columns
• 4 x 50 mm, 2 x 50 mm guard columns
• Longer 250 mm columns facilitate higher resolution separations of more complex sample matrices
• Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs

FAQs

Question: What are the guard-column dimensions?

Answer:This configuration is 4 mm ID × 50 mm long.

Question: What analytical column does it protect?

Answer:It is the guard column for the Dionex IonPac AS9-HC analytical column.

Question: What type of separation is supported?

Answer:The AS9-HC chemistry is used for carbonate-eluent anion exchange, including trace bromate and inorganic-anion analysis.

Application Note

Dionex™ IonPac™ AG9-HC is the guard column paired with the AS9-HC anion-exchange analytical column. This configuration is 4 mm ID × 50 mm long and is designed to protect the downstream analytical column from strongly retained contaminants and matrix components. The AS9-HC chemistry is a medium-capacity carbonate/bicarbonate anion-exchange system used for inorganic anions and oxyhalides, including trace bromate in drinking water. The guard column uses the same separation chemistry as the analytical column so selectivity is preserved while contamination is intercepted upstream. It is compatible with methods including U.S. EPA 300.1 and 317.0 when used as part of the appropriate IC configuration. Maximum operating pressure is specified at 4000 psi.
