描述

針對鹵乙酸的 2D-IC 測定進(jìn)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(jìn)行一維分離后對飲用水中的鹵乙酸進(jìn)行二維分離而設(shè)計(jì)。 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(yùn)行成本

  • 毛細(xì)管和微孔需要的淋洗液更少,從而降低了運(yùn)行成本

  • 優(yōu)異的色譜分析性能

  • 針對氫氧化物流動相進(jìn)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(qiáng)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(dá)到*

  • 兼容 HPLC 有機(jī)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)
