, the instrument shows repeatability to 0.001 ppb over a range of +-0.05 ppb over a 24-hour period. The system is designed to operate optimally on both normal and low-dissolved-oxygen water systems. Analysis time at 1-ppb TOC is 70 seconds +- 5 seconds. Plasma Cleaning System Anatech Springfield, VA
