的詳細介紹
IonPac CS15 Cation-Exchange Column
Medium-Capacity Cation-Exchange Column for Disparate Concentration Ratios of Sodium and Ammonium
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.
