Dionex IonPac AS11-HC 陰離子交換柱和保護(hù)柱


用 Thermo Scientific Dionex  IonPac  AS11-HC 毛細(xì)管分析和保護(hù)柱分解復(fù)雜基質(zhì)中數(shù)量眾多的無(wú)機(jī)陰離子和有機(jī)酸陰離子。 復(fù)雜的樣品基質(zhì)(例如化工廢水洗脫液和發(fā)酵肉湯溶液)含有各種無(wú)機(jī)陰離子和有機(jī)酸。 利用高容量的 Dionex IonPac AS11-HC 柱,您可以注入更高濃度的樣品,而不會(huì)出現(xiàn)柱過(guò)載或峰擴(kuò)寬。

Dionex IonPac AS11-HC 柱專門(mén)為利用氫氧化梯度在單次運(yùn)行中分解分析物而設(shè)計(jì)。 這款高容量的柱為改善一價(jià)羧酸(包括奎尼酸鹽、乳酸鹽、乙酸鹽、丙酸鹽、甲酸鹽和丁酸鹽)的分離而設(shè)計(jì)。


描述

高容量,更高分辨率

  • 需要更長(zhǎng)的保留時(shí)間,但是分辨率更高

  • 促進(jìn)良好表征的樣品中有機(jī)酸和陰離子的快速分析

  • 特別適合分解復(fù)雜樣品基質(zhì)或未表征樣品中的有機(jī)酸和陰離子

  • 建議用于一價(jià)和二價(jià)有機(jī)酸

更低的洗脫液要求,降低運(yùn)行成本

全新的 Dionex IonPac AS11-HC Capillary 柱使用與同等標(biāo)準(zhǔn)孔和微孔版本相同的填料(提供與 4 mm 和 2 mm 柱相同的性能),但僅使用 1% 的洗脫液流速,幫助降低運(yùn)行成本。

對(duì)于高離子強(qiáng)度樣品中的有機(jī)酸,使用 Thermo Scientific? Dionex? IonPac? ICE-AS1 或 ICE-AS6 柱。

用途和特點(diǎn):

 IonPac AS11-HC 陰離子交換分離柱用 NaOH或KOH做 淋 洗 液 ,用 于 無(wú) 機(jī) 陰 離 子 和有機(jī)酸陰離子的快速分離,包括:無(wú)機(jī)陰離子;一價(jià),二價(jià),三價(jià)脂肪酸;Kreb’s循環(huán)酸;高電荷陰離子,如多聚磷酸鹽,多聚硫酸鹽,多聚碳酸鹽;疏水性離子如I-,SCN-,S2O32-和ClO4-;核苷酸。有機(jī)溶劑可匹配性方便陰離子交換選擇性的控制,以及復(fù)雜基質(zhì)分析后的清洗??捎肐onPac AG11作濃縮柱。作梯度淋洗時(shí),*好在泵和進(jìn)樣閥之間連接一支陰離子捕獲柱以除去來(lái)自淋洗液中污染的陰離子。*好用EG40淋洗液發(fā)生器。IonPac AS11和高容量柱AS11-HC均有4mm標(biāo)準(zhǔn)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.
