DION ANALYSIS • 1M m I I V 1
SIMULTANEOUS ANALYSIS OF ANIONS AND CATIONS Almost any ion with pK < 7 can be analyzed by ion chromatography. Matrix effects are minimized in IC by using sample dilution as the only pretreatment. The extraordinary sensitivity of the IC has been applied to the analysis of inorganic anions such as F~, C I " S042~, aliphatic carboxylic acids such as formate and acetate, phosphonic, and small aliphatic sulfonic acids. Monovalent cation or divalent cation analyses are easily performed with separate sample injection onto different columns.

The unique dual system IC 16 enables the analyst to simultaneously determine a wide variety of ions with a single sample injection. The IC 16 contains two complete systems, each capable of operating independently or in a coupled mode. Use of different column sets in the two systems allows numerous possibilities for simultaneous ion analysis. Among these are: • anion and monovalent cation analysis • aliphatic carboxylic acids and inorganic anion analysis • aliphatic carboxylic acids and monovalent cations • monovalent and divalent cations • coupled analysis for increased specificity in anion analysis
