描述

將水分析的檢測限降低 2-5 個數(shù)量級

這些濃縮柱主要為高純水分析而設計，可以從已測得體積的水性樣品基質(zhì)中保留陰離子，從而濃縮分析物，并將檢測限降低 2-5 個數(shù)量級。

訂貨信息：

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

Determination of trace concentrations of bromate using the Dionex IonSwift MAC-200 and the Dionex IonPac? AS20 capillary column with two-dimensional ion chromatography.
