Determination of anions by non-suppressed ion chromatography using an amine column

Summary

The Synchropak AX300 column has been used to separate a wide range of anions. A standard solution containing F, Cl, NO 2 , NO 3 , HPO 4 2− , SO 4 2− ions can be analysed in 8–14 minutes using a phthalate or phthalate/citrate eluent at pH 6–7. Addition of citrate to a phthalate eluent has a pronounced effect on the times of analysis. Detection by direction and indirect UV absorption enables the analysis of a wide range of anions. Application of the technique range from rain water to ash pond liquor analysis.
