Cation Eluent Concentrates and Reagents

Cation Eluent Concentrates

The methanesulfonic acid (MSA), >99% purity, is available to prepare eluents of any concentration. The methanesulfonic acid is recommended for the preparation of the IonPac CS12, CS12A, CS14, CS15, CS16, CS17, and CS18 eluents. The eluent concentrates are recommended for fast, reliable eluent preparation.

Cation Reagents

Methanesulfonic acid and monohydrochloride (DL-2,3 diaminopropionic acid) are used for cation-exchange applications.

The methanesulfonic acid (MSA), >99% is available to prepare eluents of any concentration. The eluent concentrate is recommended for fast, reliable eluent preparation. Methanesulfonic acid is ideal for preparation of eluents for the IonPac® CS12, CS12A, CS14, CS15, CS16, and CS17 columns.

Monohydrochloride (DAP•HCl) is used for cation-exchange eluents for columns packed with sulfonated resins, including the CS3, CS10, and CS11 cation columns.

Dionex Eluent Concentrates

Dionex reagents are prepared by the dissolution of high-purity chemicals in >18.2 megohm deionized water, which was tested by ion chromatography for ionic contaminants. The bottle label states the nominal concentration value for informational purposes only. The actual concentration is within +2.5% and was determined by one or more of the following proven reliable methods of analysis such as ion chromatography, UV spectrophotometry (using NIST or USP Reference Material where applicable), titration (using NIST Reference Material), and gravimetric preparation.
