    Abstract

    This paper describes the development of an on-line analytical instrument to measure selected anions and cations over the sub-parts-per-billion to several partsper-million concentration range. The system has been designed and is being installed in an electrical generating power plant. Laboratory evaluations and limited in-plant experiences will be discussed regarding measurements of nonhydrolyzable anions and cations, transition metal ions, and organic acids. The system will accommodate multiple sample line inputs with computer-controlled options to provide sample averaging, automated sample point selection, and system standardization and calibration. The data acquisition capabilities, including storage and report generation, will also be addressed.
