产品描述
The Thermo Scientific Dionex 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 Dionex IonSwift™MAC-200 is placed between the first and second dimension of the 2D-IC system set-up. A cut volume from the first-dimension column is focused on the concentrator, then eluted onto a second-dimension column such as the Thermo Scientific Dionex IonPac AS19 or AS20 capillary column.
Features:
Ultralow-backpressure column
Compatible with the Thermo Scientific Dionex AS Autosamplers, pressurized bottles, syringes, and a single piston sample delivery pump (Thermo Scientific Dionex AXP pump)
Supports carbonate/bicarbonate, borate, and hydroxide eluents
