Dionex IonPac AS11 陰離子交換柱 044076

利用 Thermo Scientific? Dionex? IonPac? AS11 分析和保護(hù)柱,在大約 15 分鐘內(nèi)分解數(shù)量眾多的無(wú)機(jī)陰離子和有機(jī)酸。 Dionex IonPac AS11 是一種相對(duì)低容量柱,為簡(jiǎn)單樣品基質(zhì)(例如食物、飲料、化學(xué)過(guò)程溶液、廢水、鹽水和發(fā)電廠水)中無(wú)機(jī)陰離子和有機(jī)酸陰離子的快速梯度篩選而設(shè)計(jì)。

 

 

描述

優(yōu)異的色譜分析性能:

  • 促進(jìn)良好表征的樣品中有機(jī)酸和無(wú)機(jī)陰離子的快速分析

  • 特別適合高電荷陰離子,包括聚磷酸鹽和聚羧酸鹽

  • 分解復(fù)雜樣品基質(zhì)中的有機(jī)酸和無(wú)機(jī)陰離子

  • 縮短分析時(shí)間,提高通量

 

用途:
IonPac AS11 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),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。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 Fast Profiling of Inorganic Anions and Organic Acid Anions

The AS11 is a relatively low-capacity column designed for fast, gradient screening of inorganic anions and organic acid anions in simple sample matrices.

  • Fast analysis of organic acids and inorganic anions in well-characterized samples

  • Ideal for highly charged anions, including polyphosphates and polycarboxylates

  • For organic acids and inorganic anions in complex sample matrices

  • Low capacity translates into fast analysis times and high throughput

The AS11 is designed for fast profiling of inorganic anions and organic acid anions in foods, beverages, chemical process solutions, wastewater, brines, and power plant waters. The AS11 column can resolve a large number of inorganic anions and organic acids in approximately 15 minutes.
