产品简介

Dionex IonPac AS11-HC-4μm 阴离子交换柱
可在分离复杂基质中的有机酸和无机阴离子时,获得色谱分析速度和分离度的*组合。

详细介绍

Dionex IonPac AS11-HC-4μm 阴离子交换柱

使用新型 Thermo Scientific? Dionex? IonPac? AS11-HC-4μm 毛细管分析柱和保护柱,可在分离复杂基质中的有机酸和无机阴离子时,获得色谱分析速度和分离度的*组合。 这种高容量、高效率色谱柱可对复杂样品基质内的多种有机酸和无机阴离子实现分离。 与 Thermo Scientific? Dionex? IonPac? AS11-HC 色谱柱相比,这种色谱柱使用更小的树脂颗粒以提高分离效率,从而提高峰积分的准确度并获得更可靠的结果。

 

 

描述

复杂样品基质(如:化学废水以及包含各种无机阴离子和有机酸的发酵液)可使用高分辨率 Dionex IonPac AS11-HC-4μm 柱进行分析。 适用的分析物包括:

使用高容量柱可实现更高的分辨率

使用更小粒径树脂颗粒(4μm)可提高性能

使用适合您实验室的产品规格

Dionex IonPac AS11-HC-4μm 柱提供 3 种规格: 4x250 mm、2x250 mm 和 0.4x250mm。 毛细管柱可减少淋洗液消耗量,从而有助于降低运行成本。

配合高压毛细管离子色谱系统使用

用于Dionex IonPac AS11-HC-4μm 柱的更小树脂颗粒可在标准流速下产生超过 3000 psi 的反压。 在标准条件下运行该柱时,必须使用一台高压毛细管离子色谱系统,例如,Thermo Scientific? Dionex? ICS-5000+ HPIC? 或 Dionex ICS-4000 Capillary HPIC 系统。

为了获得*性能

Higher Resolution of a Large Number of Inorganic Anions and Organic Acid Anions in Complex Matrices with Smaller Particle Columns

Achieve the optimal combination of chromatographic speed and resolution using the new Thermo Scientific? Dionex? IonPac? AS11-HC-4μm anion-exchange column. This high-capacity, high-efficiency column provides excellent resolution of a large number of organic acids and inorganic anions in complex sample matrices. Compared to the previous Dionex IonPac AS11-HC column, the new anion-exchange column uses smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results. It has similar selectivity and increased peak efficiencies compared to the Dionex IonPac AS11-HC and was specifically designed to resolve a large number of inorganic anions and organic acids in a single run using a hydroxide gradient. Applications run on the Dionex IonPac AS11-HC column can be easily transferred to the Dionex IonPac AS11-HC-4μm column with the benefit of increased peak resolution, which provides more consistent results. The Dionex IonPac AS11-HC-4μm column is available in three formats; 4 × 250 mm, 2 × 250 mm and 0.4 × 250 mm. The capillary format provides reduced eluent consumption, which helps reduce operating costs.

The high-capacity Dionex IonPac AS11-HC-4μm column allows injection of more concentrated samples without column overloading or peak broadening, and provides improved separation over the Dionex IonPac AS11-HC column for monovalent carboxylic acids, including quinate, lactate, acetate, propionate, formate, and butyrate. Complex sample matrices such as chemical wastewater effluents and fermentation broth solutions containing a variety of inorganic anions and organic acids can be analyzed using the high resolution Dionex IonPac AS11-HC-4μm column.

The smaller resin particles used in the Dionex IonPac AS11-HC-4μm column produce a backpressure over 3000 psi at the standard flow rates. A high-pressure IC system, such as the Dionex ICS-5000+ HPIC or the ICS-4000 Capillary HPIC is required to operate this column under standard conditions.
