✦ Synopsis

Inorganic anions can be determined in natural waters using high-performance ion-exchange chromatography. Single-column ion chromatography has been used to minimize the instrumentation, total time and cost requirements of such analyses. The analysis speed can be enhanced through the use of shorter columns without significant losses in efficiency. Anions has been analysed using an "Ion-Guard" cartridge (30 mm x 4.6 mm) which is normally employed as a guard column of sample preconcentrator. Utilization of such cartridges is recommended for high-speed analysis of anions in relatively uncomplicated aqueous samples.
