利用 Thermo Scientific? Dionex? IonPac? CS17 柱在对不含有机溶剂的复杂基质中的疏水胺分析时可实现的选择性和峰形。 该款中等容量、带羧酸盐官能团的色谱柱经优化,适用于使用简单的水性淋洗液在高温下 (40?C) 对疏水胺和多价胺进行梯度分离。 产品适用于对使用铵盐、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;工业溶剂和食品样本进行分析。
对多种基质中的常见阳离子和小极性胺类进行梯度分离
疏水性、低容量色谱柱经优化,适合对复杂样品基质中的多价和疏水胺(包括烷醇胺和jia胺)进行梯度分离
分离中等疏水性的胺类,包括生物胺、烷基二胺和聚胺。
基线漂移小,且分析物检测灵敏度得到改善
无须使用溶剂,改善 Thermo Scientific? Dionex? IonPac? CS14、CS15 和 CS16 柱多数胺类应用的峰形
经优化,可轻松用于酸性梯度应用
兼容有机溶剂,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 CS17 毛细管柱提供的性能与标准孔和微孔 Dionex IonPac CS17 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
4x250 mm、2x250 mm 分析柱
4x50 mm、2x50 mm 保护柱
0.4x250mm 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:
CS17柱用于分离多价和疏水性的胺类,包括烷基胺、二胺类、和生物胺。样品基体包括环境水样,用胺处理过的电厂水样,吗啉,或乙醇胺,化学添加剂,化学过程溶液,洗涤液,电镀液以及溶剂。CS17柱容量中等(1.45meq/col),兼容有机溶剂,但不需要添加有机溶剂即可分离胺类化合物。

The Thermo Scientific Dionex IonPac* CS17 carboxylate-functionalized cation-exchange column is tailored for gradient separation of polyvalent and moderately hydrophobic amines, including biogenic amines and diamines, using simple aqueous eluents and elevated temperature (40 °C). The Dionex IonPac CS17 is an excellent column for use with Reagent-Free* IC systems using eluent generation, which requires only a deionized water source to produce methanesulfonic acid eluent. The Dionex IonPac CS17 column is now available in capillary format (0.4 × 250 mm) offering reduced eluent consumption and reduced operating costs.
For polyvalent and moderately hydrophobic amines, including diamines and biogenic amines
Optimized for simple acidic gradient applications with minimal baseline shift
Ideal alternative for amine applications using the Dionex IonPac CS14 column
Provide improved peak shape without adding organic solvent to the eluents
Compatible with organic solvents
The Dionex IonPac CS17 column is recommended for separation of polar amines including alkanolamines and methylamines. It can also be used for separation of moderately hydrophobic amines, including biogenic amines, alkyldiamines, and polyamines. 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 Dionex IonPac CS17 column is also used extensively in the food industry.
The Dionex IonPac CS17 column offers improved peak shapes and efficiencies for Dionex IonPac CS14 amine applications. Solvent compatibility permits solvent use for elution of more hydrophobic amines and easy column cleanup after the analysis of complex sample matrices. Use the Dionex IonPac CS17 column with eluent generation for simplified methanesulfonic acid eluent preparation.
