Dionex IonPac CS19-4µm 阳离子交换柱

Dionex IonPac CS19-4μm 阳离子交换柱

使用新型 Thermo Scientific? Dionex? IonPac? CS19-4μm 毛细管柱、分析柱和保护柱，可在色谱分析速度和高分辨率之间达到最佳平衡。 这种高载量、高分辨率并带有羧酸盐官能团的色谱柱可对常见阳离子、小分子极性胺以及复杂样品基质（如：使用氨、吗啉或乙醇胺处理过的发电厂废水、化学添加剂、化学加工溶液、洗涤液、个人护理品、食品样本）中的多价胺实现卓越分离。

描述

与 Thermo Scientific? Dionex? IonPac? CS19 色谱柱相比，这种色谱柱使用更小的树脂颗粒以提高分离效率，从而提高峰积分的准确度并获得更可靠的结果。

对各种基质内的常见阳离子和小分子极性胺实现最高分辨率的分离

• 通过使用更小的树脂颗粒，可对复杂样品基质内的常见阳离子和小分子极性胺实现最高分辨率的分离

• 峰效率提高且分辨率增加，从而实现更加一致的积分并获得更可靠的结果

• 由于选择性相似，因此可将基于 Dionex IonPac CS19 柱的应用轻松转移至 4 μm 柱

• 可对小分子极性胺（包括链烷醇胺和甲胺）以及中等疏水性胺和多价胺（包括生物胺和烷基二胺）进行简单梯度分离

• 高载量便于进样高浓度样品，同时不会导致柱过载或峰展宽

• 与适量有机溶剂相容（不包括醇类），从而可增强分析物的溶解度，改变柱选择性，并且有助于有效清洁色谱柱

配合高压离子色谱系统使用 
通过使用更小的树脂颗粒，可达到更高的分辨率，并在标准流速下产生超过 3000 psi 的柱反压。 一台高压离子色谱系统（如：Thermo Scientific? Dionex? ICS-5000+ HPIC? 或 Dionex ICS-4000 Capillary HPIC 系统）是在标准条件下运行该色谱柱并发挥流速高和运行时间短等优势的必要设备。

洗脱液需要量减少，从而降低了运行成本 
由于使用相同的填料，因此 Dionex IonPac CS19-4μm 毛细管柱可提供与标准孔和微孔 Dionex IonPac CS19-4μm 柱相同的性能。 由于毛细管系统运行的洗脱液流速仅为标准孔系统的 1%，需要的洗脱液更少，产生的废物也更少，从而降低运行成本。

提供多种规格，实现应用灵活性

• 4x250 mm、2x250 mm 分析柱

• 4x50 mm、2x50 mm 保护柱

• 0.4x250 mm 毛细管柱、0.4x50mm 毛细管保护柱

• 更长的 250 mm 柱，实现更复杂样品基质的更高分辨率分离

• 更小柱内径，提高质量灵敏度，节省洗脱液和试剂，并且降低运行成本

High Resolution, High-Capacity Cation-Exchange Column for the Separation of Small Polar Amines

Attain the optimal combination of chromatographic speed and resolution using the new Thermo Scientific? Dionex? IonPac? CS19-4μm cation-exchange column. This high capacity, high resolution capillary column provides excellent resolution of common cations, small polar amines and polyvalent amines in complex sample matrices. Compared to the previous Dionex IonPac CS19 column, the new ion-exchange column uses smaller resin particles for more efficient separations resulting in faster analysis, more accurate peak integration, and more reliable results.

The Dionex IonPac CS19-4μm carboxylate-functionalized cation-exchange column has similar selectivity to the Dionex IonPac CS19 column for the six common cations, small polar amines (including alkanolamines and methylamines) and moderately hydrophobic and polyvalent amines (including biogenic amines and alkyl diamines). Applications run on the Dionex IonPac CS19 column can be easily transferred to the Dionex IonPac CS19-4μm column with the benefit of increased peak resolution which provides more consistent results. The Dionex IonPac CS19-4μm column is available in three formats, standard bore (4 × 250 mm), microbore (2 × 250 mm), and capillary  (0.4 × 250 mm). The capillary and microbore formats require less eluent thereby reducing operating costs.

• Increase speed, chromatographic resolution and quality of analytical results

• For analysis of amines including alkanolamines and methylamines in diverse sample matrices

• For analysis of moderately-hydrophobic amines including biogenic amines, alkyl diamines, and polyvalent amines

• Optimized for fast simple acidic gradient separations with minimal baseline shift

• High capacity allows routine analysis of high-ionic-strength samples

The Dionex IonPac CS19-4μm column is targeted for analysis of power plant waters treated with ammonium, morpholine, or ethanolamine; as well as chemical additives; chemical process solutions; scrubber solutions; personal care products; and food samples.

The smaller resin particles used in the Dionex IonPac CS19-4μm column produce increased backpressure. When operating the Dionex IonPac CS19-4μm microbore or capillary column at standard flow rate, 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 IC system, such as the Thermo Scientific Dionex ICS-5000⁺ HPIC or Dionex ICS-4000 HPIC is required. The Dionex ICS-5000⁺ HPIC system is required for standard operation of the Dionex IonPac CS19-4μm standard bore column.
