的詳細介紹
IonPac CS16 Cation-Exchange Column
High-Capacity Carboxylate-Functionalized Column for Disparate Sodium and Ammonium Concentrations
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.
