| | | IonPac CS15 Cation-Exchange Column |  | The IonPac® CS15 is a high-capacity, cation-exchange column designed for the determination of disparate concentration ratios of sodium and ammonium in diverse sample matrices. The new CS16 column is the column of choice for disparate concentration ratios of sodium and ammonium, and requires only an aqueous acid eluent for the analysis. The CS15 can be used for disparate concentrations of sodium and ammonium. Solvent and elevated temperature are required for this separation. The CS15 is recommended for trace ethanolamine in high-ammonium or high-potassium concentrations. The CS15 can also be used for alkanolamines. The CS16 column provides improved performance for disparate concentration ratios of sodium and ammonium without solvent in the eluent. 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.
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 be determined. Use the Cation Self-Regenerating Suppressor (CSRS® ULTRA) with the CS15 column.

| SRS 300 |  | The Self-Regenerating Suppressor, (SRS® 300), is used for electrolytically regenerated suppression of ion chromatography applications requiring high capacity, fast start-up, and sensitivity. |
| RFC-10 and RFC-30 |  | Want to stop manually preparing eluent and regenerants? Reagent-FreeTM IC with Eluent Generation (RFIC-EGTM ) systems reduce errors and provide consistency in your results, all by just adding water. The RFC-30 allows users to upgrade existing systems to RFIC-EG systems at a reasonable price. |
