Dionex IonPac CS11 阳离子交换柱
为使用盐酸 (HCl) 和二氨基丙酸 (DAP) 淋洗液对无机阳离子进行等度分离选择 Thermo Scientific? Dionex? IonPac? CS11 分析和保护柱。 该款色谱柱的选择性与 IonPac CS10 柱相似，但灵敏度有所改善，且因为使用更小的 2mm 内径规格，淋洗液用量更小。
Dionex IonPac CS11 柱可用于测定多种样品基质中的常见无机阳离子和脂肪胺以及芳香胺，但是阳离子交换柱技术的发展使得在进行这些分离时有更好的色谱柱可供选择。
推荐的阳离子交换柱
自首次推出 Dionex IonPac CS11 柱后，Dionex 已经推出了数款包含高级功能的新型阳离子交换柱。 例如，多数现代 Dionex IonPac 阳离子交换柱使用简单的甲磺酸淋洗液，而不是 DAP-HCl 淋洗液。 这些色谱柱及其推荐用途罗列如下。
Dionex IonPac CS12A 柱改善了快速分析多种基质中无机阳离子和铵的性能。
Dionex IonPac CS17 柱推荐用于疏水和多价胺。
Dionex IonPac CS19 和 CS19-4μm 柱推荐用于极性胺分析，包括烷醇胺和甲胺，以及中等疏水性胺和多价胺。
兼容有机溶剂以增强分析物溶解度，改变柱选择性，或者便于有效的柱清洁
提供多种规格，实现应用灵活性
2x250mm 分析柱

The IonPac CS11 is designed for the isocratic separation of inorganic cations using hydrochloric acid with diaminopropionic (DAP) acid eluents.
The CS11 can be used for analysis of common inorganic cations and aliphatic, cyclic, and aromatic amines.
Compatible with organic solvents.
The CS12A improves performance for fast analysis of inorganic cations and ammonium.
The CS17 column is recommended for hydrophobic and polyvalent amines.
The CS18 column is recommended for polar amines including alkanolamines and methylamines.
The CS18 is also recommended for moderately hydrophobic amines and polyvalent amines.
The CS11 is useful in determining common inorganic cations and aliphatic and aromatic amines in diverse sample matrices, including environmental and drinking waters, power plant waters treated with ammonium, soil extracts, acid digests, chemical additives, chemical process solutions, scrubber solutions, plating baths, and industrial solvents.
The CS11 has selectvitiy similar to the CS10 column, with improved sensitivity and lower eluent consumption due to its smaller 2 mm i.d. format.
Note: Use the Cation MicroMembrane Suppressor (CMMS? 300) with the CS11 column. Electrolytic suppression is not recommended with HCl and DAP eluents.
