Dionex IonPac AS11-HC-4μm 陰離子交換柱

使用新型 Thermo Scientific? Dionex? IonPac? AS11-HC-4μm 毛細管分析柱和保護柱，可在分離復(fù)雜基質(zhì)中的有機酸和無機陰離子時，獲得色譜分析速度和分離度的*組合。 這種高容量、高效率色譜柱可對復(fù)雜樣品基質(zhì)內(nèi)的多種有機酸和無機陰離子實現(xiàn)分離。 與 Thermo Scientific? Dionex? IonPac? AS11-HC 色譜柱相比，這種色譜柱使用更小的樹脂顆粒以提高分離效率，從而提高峰積分的準確度并獲得更可靠的結(jié)果。

描述

復(fù)雜樣品基質(zhì)（如：化學(xué)廢水以及包含各種無機陰離子和有機酸的發(fā)酵液）可使用高分辨率 Dionex IonPac AS11-HC-4μm 柱進行分析。 適用的分析物包括：

• 一價和二價有機酸

• 復(fù)雜樣品基質(zhì)或未知樣品中的有機酸和無機陰離子

使用高容量柱可實現(xiàn)更高的分辨率

• 便于進樣更高濃度樣品，同時不會導(dǎo)致柱過載或峰展寬

使用更小粒徑樹脂顆粒（4μm）可提高性能

• 可將應(yīng)用從 Dionex IonPac AS11-HC 柱輕松轉(zhuǎn)移至 4μm 柱

• 選擇性與 Dionex IonPac AS11-HC 柱相似

• 色譜峰分辨率提高，結(jié)果更*

• 可改善一價羧酸（包括奎尼酸鹽、乳酸鹽、乙酸鹽、丙酸鹽、甲酸鹽和丁酸鹽）的分離效果

使用適合您實驗室的產(chǎn)品規(guī)格

Dionex IonPac AS11-HC-4μm 柱提供 3 種規(guī)格： 4x250 mm、2x250 mm 和 0.4x250mm。 毛細管柱可減少淋洗液消耗量，從而有助于降低運行成本。

配合高壓毛細管離子色譜系統(tǒng)使用

用于Dionex IonPac AS11-HC-4μm 柱的更小樹脂顆粒可在標準流速下產(chǎn)生超過 3000 psi 的反壓。 在標準條件下運行該柱時，必須使用一臺高壓毛細管離子色譜系統(tǒng)，例如，Thermo Scientific? Dionex? ICS-5000+ HPIC? 或 Dionex ICS-4000 Capillary HPIC 系統(tǒng)。

為了獲得*性能

• 請使用 Thermo Scientific? Dionex? IonPac? AS11 柱，對已知樣品中的有機酸和陰離子進行快速分析

• 對于高離子強度樣品中的有機酸，請使用 Thermo Scientific? Dionex? IonPac? ICE-AS1 或 ICE-AS6 柱

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.

• Increase chromatographic resolution and quality of results

• Use for organic acids and inorganic anions in complex sample matrices or uncharacterized samples

• Recommended for monovalent and divalent organic acids

• Use the Dionex IonPac AS11 column 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-pressure Thermo Scientific Dionex ICS-5000⁺ HPIC^? or ICS-4000 HPIC system is required to run at standard flow rates.

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.
