Dionex IonPac CS16 阳离子交换柱
利用 Thermo Scientific? Dionex? IonPac? CS16 毛细管分析和保护柱测定多种样品基质中浓度差异极大的邻近阳离子（如钠离子和铵离子）。 样品基质包括环境水样；使用铵盐、吗啉或乙醇胺处理的发电厂水；化学添加剂；化学加工溶液；洗涤液；电镀槽和工业溶剂。 Dionex IonPac CS16 柱专为用于 Thermo Scientific? Dionex? IonPac? CS15 柱多数应用而设计，因其较大的线性工作范围也推荐用于此类应用。
在测定差异极大的钠离子和铵离子比例时可实现卓越性能
专为测定多种样品基质中差异极大的邻近洗脱阳离子（如钠离子和铵离子）浓度比例而优化。
在存在锂、钠、铵、钾、镁和钙的情况下，测定复杂样品基质中的短链烷基胺和烷醇胺。
使用等度酸淋洗液，在少于 20 钟内分离比例最高达 10,000:1 的钠离子和铵离子。
使用梯度甲磺酸 (MSA) 淋洗液分离比例最高达 20,000:1 的钠离子和铵离子。
高容量色谱柱可改善样品装载量和峰分辨率
在 40?C 的最佳操作温度下达到最大峰效率
分析低 pH 值样品的最佳羧酸盐官能团色谱柱
兼容有机溶剂（不包括乙醇），以增强分析物溶解度，优化柱选择性，便于有效的柱清洁
更低的淋洗液要求，降低运行成本
由于使用相同的填料，Dionex IonPac CS16 毛细管柱提供的性能与标准孔和微孔 Dionex IonPac CS16 柱相同。 由于毛细管系统运行的淋洗液流速仅为标准孔系统的 1%，需要的淋洗液更少，产生的废液也更少，从而降低了运行成本。
提供多种规格，实现应用灵活性
5x250mm、2x250mm 分析柱
5x50mm、2x50mm 保护柱
0.5x250mm 毛细管柱、0.5x50mm 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
更小柱内径提供更高质量灵敏度，节省淋洗液和试剂，从而降低运行成本。
用途和特点：
IonPac CS16是高容量，羧酸功能基的阳离子交换分离柱，用于等度分离浓度比悬殊的Na+和Li+（浓度比可达10，000：1）；以及分析复杂基质中的短碳链烷基胺和烷醇胺。IonPac CS16基本适用于IonPac CS15的分析范围。IonPac CS16柱在40℃时分离效果最好。有机溶剂可匹配方便清洗柱子。

The IonPac? CS16 is the column of choice for disparate concentration ratios of adjacent eluting cations such as sodium and ammonium in diverse sample matrices. The high-capacity, high-resolution CS16 column can be used for short-chained amines, including alkylamines and alkanolamines, in diverse sample matrices. The CS16 column is now available in capillary format (0.5 × 250 mm) offering reduced eluent consumption and reduced operating costs.
For disparate concentration ratios of close-eluting cations such as ammonium and sodium in complex matrices
Ideal for trace-level ammonium in high concentrations of sodium
Ideal for trace-level sodium in high concentrations of ammonium or amines
Best carboxylate-functionalized column to tolerate samples with low pH
Isocratic acid eluent and elevated temperature (40 °C) required for sodium: ammonium ratios to 1:10,000
Gradient MSA eluent and elevated temperature required for sodium: ammonium ratios up to 1:20,000
Useful for short-chained amines, including alkylamines and alkanolamines
Compatible with organic solvents excluding alcohols
Using an isocratic acid eluent and elevated temperature (40 °C) coupled with suppressed conductivity, ratios up to 10,000:1 of sodium and ammonium can be resolved in less than 20 min. Sample matrices include environmental waters; power plant waters treated with ammonium, morpholine or ethanolamine; chemical additives; chemical process solutions; scrubber solutions; plating baths; and industrial solvents. The CS16 is designed for use in most IonPac CS15 applications.
The CS16 column has the highest capacity among Dionex carboxylate-based cation columns, resulting in improved loadability and resolution. Use the CS16 with the Eluent Generator for simplified, consistent methanesulfonic acid eluent preparation. Use the Cation Self-Regenerating Suppressor (CSRS? 300) with standard or microbore CS16 columns or the Cation Capillary Electrolytic Suppressor (CCES? 300) with the CS16 capillary column.
