Dionex IonPac AS11-HC
毛细管分析和保护柱
利用
Thermo Scientific Dionex IonPac AS11-HC 毛细管分析和保护柱分解复杂基质中数量众多的无机阴离子和有机酸阴离子。
复杂的样品基质(例如化工废水洗脱液和发酵肉汤溶液)含有各种无机阴离子和有机酸。 利用高容量的 Dionex IonPac AS11-HC
柱,您可以注入更高浓度的样品,而不会出现柱过载或峰扩宽。
Dionex
IonPac AS11-HC 柱专门为利用氢氧化梯度在单次运行中分解分析物而设计。
这款高容量的柱为改善一价羧酸(包括奎尼酸盐、乳酸盐、乙酸盐、丙酸盐、甲酸盐和丁酸盐)的分离而设计。
描述
高容量,更高分辨率
更低的洗脱液要求,降低运行成本
全新的
Dionex IonPac AS11-HC Capillary 柱使用与同等标准孔和微孔版本相同的填料(提供与 4 mm 和 2 mm 柱相同的性能),但仅使用
1% 的洗脱液流速,帮助降低运行成本。
对于高离子强度样品中的有机酸,使用
Thermo Scientific? Dionex? IonPac? ICE-AS1 或 ICE-AS6 柱。
用途和特点:
IonPac AS11-HC 阴离子交换分离柱用 NaOH或KOH做 淋 洗 液 ,用 于 无
机 阴 离 子
和有机酸阴离子的快速分离,包括:无机阴离子;一价,二价,三价脂肪酸;Kreb’s循环酸;高电荷阴离子,如多聚磷酸盐,多聚硫酸盐,多聚碳酸盐;疏水性离子如I-,SCN-,S2O32-和ClO4-;核苷酸。有机溶剂可匹配性方便阴离子交换选择性的控制,以及复杂基质分析后的清洗。可用IonPac
AG11作浓缩柱。作梯度淋洗时,最好在泵和进样阀之间连接一支阴离子捕获柱以除去来自淋洗液中污染的阴离子。最好用EG40淋洗液发生器。IonPac
AS11和高容量柱AS11-HC均有4mm标准孔柱和2-mm微孔柱。

For Resolving a Large Number of Inorganic Anions and Organic Acid Anions in
Complex Matrices
Complex sample matrices such as chemical wastewater effluents and
fermentation broth solutions contain a variety of inorganic anions and organic
acids. The Thermo Scientific* Dionex* IonPac* AS11-HC column was specifically
designed to resolve a large number of inorganic anions and organic acid anions
in a single run using a hydroxide gradient. The new Dionex IonPac AS11-HC
Capillary Column is packed with the same material as the equivalent standard
bore and microbore versions (providing the same performance as a 4 mm and 2 mm
column) but requires only 1/100th the eluent flow rate. The capillary format
provides the advantage of significantly reduced eluent consumption, which helps
reduce operating costs
Use for organic acids and anions in complex sample matrices or
uncharacterized samples.
Recommended for monovalent and divalent organic acids.
Use the Dionex Ionpac AS11 for fast analysis of organic acids and anions in
well-characterized samples.
Use the Dionex IonPac ICE-AS1 or ICE-AS6 columns for organic acids in
high-ionic-strength samples.
High capacity translates into longer retention times, but with higher
resolution.
The high-capacity Dionex IonPac AS11-HC column allows the injection of more
concentrated samples without column overloading or peak broadening, and provides
improved separation over the Dionex IonPac AS11 column for monovalent carboxylic
acids, including quinate, lactate, acetate, propionate, formate, and
butyrate.
