The Thermo Scientific IonSwift™ MAC-200 Monolith Anion Concentrator Column is a monolithic anion-exchange concentrator column with very low void volume (approximately 23 µL). This ultraclean (low sulfate) concentrator column is designed primarily for 2D-IC capillary applications including trace bromate or perchlorate in drinking water matrices. The MAC-200 is placed between the first and second dimension of the 2D-IC system set-up and a cut volume is focused on the MAC-200, then eluted onto a second dimension column such as the IonPac AS19 or AS20 capillary column. The MAC-200 concentrator column can also be used to preconcentrate trace anions in high purity water matrices. It strips ions from a measured volume of aqueous sample matrix, concentrating the analyte species and lowering detection limits.

• Ultralow-backpressure column
• Compatible with the AS Autosamplers, pressurized bottles, syringes, and a single piston sample delivery pump (AXP pump)
• Supports carbonate/bicarbonate, borate, and hydroxide eluents
