Dionex IonPac CS18 阳离子交换柱 062878

利用 Thermo Scientific? Dionex IonPac CS18 阳离子交换柱分离极性胺。 该款低容量、带羧酸盐官能团的色谱柱专为使用简单水性淋洗液在升高温度下分离常见阳离子、极性小分子胺和中等疏水性的多价阴离子进行优化。 不过,新款 Thermo Scientific? Dionex? IonPac? CS19 或 Dionex IonPac CS19-4μm 阳离子交换柱是这些应用的推荐色谱柱。

 

 

描述

利用抑制型和非抑制型电导检测器进行阳离子和胺分离

  • 低容量色谱柱经优化,适用于极性胺、中等疏水性胺和多价阳离子的等度和梯度分离

  • 可以配合抑制型和非抑制型电导检测器使用

  • 对于铵或弱碱,推荐使用非抑制型电导检测器以扩展校准线性

  • 也可用于 Dionex IonPac SCS-1 柱支持的多种非抑制型应用,但柱稳定性更佳

  • 经优化,可轻松用于酸性梯度分离,基线漂移极小

  • 低容量便于中等浓度的酸淋洗液将多价阳离子洗脱出来

  • 与适量有机溶剂相容(不包括醇类),以增强分析物溶解度,优化柱选择性,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

  • 2x50mm 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

Low-Capacity Cation-Exchange Column for the Separation of Polar Amines

The IonPac? CS18 carboxylate-functionalized cation-exchange column is tailored for the separation of polar amines including alkanolamines and methylamines, and moderately hydrophobic and polyvalent amines including biogenic amines and alkyl diamines, using simple aqueous eluents and elevated temperature. The CS18 is ideally used with RFIC systems for automatic methanesulfonic acid eluent generation.

  • For amines including alkanolamines and methylamines in diverse sample matrices

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

  • Optimized for simple acidic gradient separations with minimal baseline shift

  • Ideal Reagent-Free electrolytic suppression with the Cation Self-Regenerating Suppressor CSRS? 300

  • Compatible with moderate amounts of organic solvents, excluding alcohols

  • Requires only a modest acid concentration to elute polyvalent cations

The IonPac CS18 cation-exchange column supports isocratic and gradient separations of polar amines, moderately hydrophobic amines, and polyvalent cations using suppressed conductivity detection. The CS18 column with nonsuppressed conductivity detection is recommended when extended calibration linearity for ammonium or weak bases is required. The CS18 can be used for many of the nonsuppressed applications supported by the IonPac SCS-1 column but with much greater column stability.

The IonPac CS18 is targeted for analysis of power plant waters treated with ammonium, morpholine, or ethanolamine; chemical additives; chemical process solutions; scrubber solutions; personal care products; and food samples.

Note: Use the Cation Self-Regenerating Suppressor (CSRS 300) with the CS18 column.
