产品简介

Dionex IonPac AS18-4μm 阴离子交换柱
可在色谱分析速度和分辨率之间达到*平衡。

详细介绍

Dionex  IonPac  AS18-4μm 阴离子交换柱

 

使用新型 Thermo Scientific? Dionex? IonPac? AS18-4μm 阴离子交换柱,可在色谱分析速度和分辨率之间达到*平衡。 这种高载量、高效率色谱柱可对不同样品基质中的无机阴离子实现分离。 这是首xuan的氢氧化物选择性色谱柱,可按照美国 EPA 方法 300.0 (A) 和 300.1,对饮料和废水样品中的无机阴离子进行较快速的合规监测。 与 Thermo Scientific? Dionex? IonPac? AS18-Fast 色谱柱相比,新型 Dionex IonPac AS18-4μm 阴离子交换柱可使用更小的树脂颗粒以提高峰效率,从而缩短运行时间、提高峰积分的准确度并获得更可靠的结果。

 

 

 

描述

分离常见无机阴离子的速度zui快并且分辨率极jia

通过使用更小的树脂颗粒和更短的柱规格,这种色谱柱可提供zui高的峰效率并能对常见无机阴离子实现*分离,因此可用于环境水体的快速分析。

分析各种基质中的常见无机阴离子和低分子量有机酸

在高压离子色谱系统中使用 4μm 柱

通过使用更小的树脂颗粒,可达到更高的分辨率,并产生超过 3000 psi 的柱反压。 当在 10μL/min 的标准流速下运行 Dionex IonPac AS18-4μm 毛细管柱时,一台能够在高达 3000 psi 的压力下运行的离子色谱系统*够用。 然而,为了发挥快速色谱运行的优势,在使用高流速时,需要一台高压毛细管离子色谱系统,例如,Thermo Scientific? Dionex? ICS-5000+ HPIC 或 Thermo Scientific? Dionex? ICS-4000 HPIC。 Dionex IonPac AS18-4μm 微孔柱和标准孔柱正常工作时,Dionex ICS-5000+ HPIC 系统*。

使用适合您实验室的产品规格

较短的 150mm AS18-4μm 色谱柱有助于加快运行速度,同时较小的粒径可保持更高分辨率的分离;保护柱有 3 种规格可选:

毛细管柱的淋洗液需要量减少,从而降低了运行成本

毛细管柱可通过节省淋洗液而显著降低运行成本和废液处置成本。 Dionex IonPac AS18-4μm 毛细管柱与对应的标准孔柱和微孔柱装填同种材料,从而可提供相同的性能。 由于运行毛细管系统时的淋洗液流速仅为标准孔系统的 1%,因此运行成本得以降低。 毛细管柱可与 Thermo Scientific? Dionex? ICS-4000 和 ICS-5000+ 毛细管系统配合使用。

需要更高的分辨率还是更快的分离速度?

Fast, High-Resolution Determination of Inorganic Anions and Low-Molecular-Weight Organic Acids

Attain the optimal combination of chromatographic speed and resolution using the new Thermo Scientific Dionex IonPac AS18-4μm anion-exchange column. This high-capacity, high-efficiency column provides excellent resolution of inorganic anions in diverse sample matrices. Compared to the previous Dionex IonPac AS18-Fast column, the new ion-exchange column uses smaller resin particles for more efficient separations resulting in faster run times, more accurate peak integration and more reliable results.The Dionex IonPac AS18-4μm anion-exchange column is the hydroxide-selective column of choice for compliance monitoring of inorganic anions in drinking water and wastewater samples in accordance with US EPA Methods 300.0 (A) and 300.1. 

The new Dionex IonPac AS18-4μm column offers the same selectivity as the Dionex IonPac AS18-Fast column, but with the reduced particle size, this column can separate the common inorganic anions in significantly less time without loss of resolution. Applications run on the Dionex IonPac AS18-Fast column can be easily transferred to the Dionex IonPac AS18-4μm column with the benefit of reduced run time with no loss in resolution. The Dionex IonPac AS18-4μm column is available in capillary format (0.4 × 150 mm), microbore format (2 × 150 mm) and standard bore format (4 × 150 mm). The capillary format offers the advantage of reduced eluent consumption, thereby lowering operating costs.  

The smaller resin particles used in the Dionex IonPac AS18-4μm column produce increased back pressure. When operating the Dionex IonPac AS18-4μm capillary column at the standard flow rate of 0.010 mL/min, an IC system capable of operating up to 3000 psi is sufficient. However, to take advantage of the fast runs, using elevated flow rates, a high pressure capillary IC system, such as the Thermo Scientific Dionex ICS-5000+ HPIC or the Thermo Scientific Dionex ICS-4000 HPIC is required. The Dionex ICS-5000+ HPIC systems is required for standard operation of the Dionex IonPac AS18-4μm microbore and standard bore columns.
