Organic acid eluents for single-column ion chromatography

Organic acid eluents for single-column ion chromatography

Various organic acids are tested for use as eluents in single-column anion chromatography. Adsorption and dissociation characteristics of the acids are related to eluent strength and selectivity variations. Sensitivities and background conductances of these eluents are also compared to other common...

Zusammenfassung:Various organic acids are tested for use as eluents in single-column anion chromatography. Adsorption and dissociation characteristics of the acids are related to eluent strength and selectivity variations. Sensitivities and background conductances of these eluents are also compared to other common eluents used in single-and dual-column anion chromatography. Conclusions are drawn concerning the selection and advantages of acid eluents. 9 references, 3 figures, 7 tables.
