利用 Thermo Scientific? Dionex IonPac AS26 柱，以高靈敏度分離飲用水樣品中的鹵乙酸和溴酸鹽。在二維 IC (2D-IC) 方法的二維分離中使用該款高容量氫氧化物選擇性陰離子交換柱時，可檢測低 μg/L (ppb) 水平的鹵乙酸。

描述

針對鹵乙酸的 2D-IC 測定進行了優(yōu)化

Dionex IonPac AS26 毛細(xì)管柱專為在使用如 Thermo Scientific? Dionex? IonPac? AS24A 4x250mm 柱等色譜柱進行一維分離后對飲用水中的鹵乙酸進行二維分離而設(shè)計。該款色譜柱也可用于測定痕量溴酸鹽，同時適用于使用梯度洗脫的 Reagent-Free 離子色譜 (RFIC?) 系統(tǒng)的特殊應(yīng)用開發(fā)。

降低運行成本

毛細(xì)管和微孔需要的淋洗液更少，從而降低了運行成本
優(yōu)異的色譜分析性能
針對氫氧化物流動相進行優(yōu)化
高容量： 250μeq 每柱 (4x250mm)
在 2D-IC 中無需樣品預(yù)處理即可測定高離子強度基質(zhì)中的鹵乙酸
可在室溫或高溫環(huán)境下操作；選擇性在 15oC 操作溫度下達到*
兼容 HPLC 有機溶劑

For Separation of Haloacetic Acids and Bromate in Drinking Water Using Two-Dimensional Ion Chromatography (2D-IC) Analysis

The Thermo Scientific Dionex IonPac^* AS26 hydroxide-selective anion-exchange column is specifically designed for 2D-IC separation of haloacetic acids (HAAs) in drinking water. The capacity and selectivity of this column enables analysis of haloacetic acids in drinking water at low-μg/L concentrations. The Dionex IonPac AS26 column is available in standard bore (4 × 250 mm), microbore (2 × 250 mm), and capillary (0.4 × 250 mm) formats, supporting flow rates from 10 μL/min to 3 mL/min.

High capacity: 250 μeq per column (4 × 250 mm)
Determines HAAs in high-ionic-strength matrices without sample pretreatment
Column selectivity optimized for a 15 oC operating temperature
Compatible with HPLC organic solvents
Used as second-dimension column in 2D-IC method for HAAs (0.4 × 250 mm)
