Dionex IonPac CS15 阳离子交换柱
利用 Thermo Scientific? Dionex? IonPac? CS15 阳离子交换柱测定多种样品基质中差异极大的乙醇胺和铵离子浓度比例时获取一致可靠的结果。 这是一款中等容量、带羧酸盐官能团的阳离子交换柱，带冠醚基团。 此款色谱柱具有独特的选择性，是基于羧酸的 Dionex 阳离子交换柱中唯一一款乙醇胺先于铵离子流出的色谱柱。 因此，这是分析含高浓度铵离子和低浓度乙醇胺样品的首选色谱柱。
Dionex IonPac CS15 柱也可分离浓度比例差异极大的钠离子和铵离子，不过，先进的 Thermo Scientific? Dionex? IonPac? CS16 阳离子交换柱更推荐用于该应用。

The IonPac? CS15 is a medium-capacity carboxylate-functionalized cation-exchange column with crown ether moiety for the determination of disparate concentration ratios of sodium and ammonium in diverse sample matrices.
Solvent and elevated temperature required for more efficient ammonium and potassium peaks
Use the CS16 column for separating disparate concentrations of sodium and ammonium without an organic solvent
Useful for determination of trace ethanolamine in highammonium or high-potassium concentrations
Useful for separating alkanolamines and other small amines
The crown ether moiety gives it unique selectivity, and may offer an advantage for certain types of matrices
Compatible with organic solvent
The IonPac CS15 has unique selectivity, and is the only carboxylic acid based cation column from Dionex in which ethanolamines elute before ammonium. Thus, for samples with high ammonium to low ethanolamine ratios, the CS15 is the column of choice. Using an isocratic acid or solvent eluent and elevated temperature (40 °C), coupled with suppressed conductivity detection, ratios of up to 8000:1 of sodium and ammonium can also be determined.
Sample matrices include environmental waters; power plant waters treated with ammonium, morpholine or ethanolamine; chemical additives; chemical process solutions; scrubber solutions; plating baths; industrial solvents; and soil matrices. The CS15 is also particularly useful for matrices with high potassium concentrations. Use the Cation Self-Regenerating Suppressor (CSRS? 300) with the CS15 column.
Note: See the IonPac CS16 for improved performance without using solvent.
