On-line analysers for ultrapure water monitoring
November 2014Analytical Instrumentation & Environmental Monitoring
As power plants continue to grow in size and equipment becomes more expensive, it is crucial to monitor and manage the quality of the pure water used in the power cycle. High levels of sodium and silica can damage equipment like boilers and turbines leading to expensive maintenance as well as unplanned shutdowns. That is why it is essential to ensure that these levels are the lowest possible and to have an early warning in case levels start to rise.
Mettler Toledo Thornton offers sodium and silica analysers with fully unattended, automatic calibration to minimise operator error and provide reliable measurements at extremely low concentration levels.
The Thornton 2300Na sodium and 2800Si silica analysers provide efficient and reliable monitoring of low contaminant concentrations for pure water treatment in microelectronics and power cycle chemistry applications. They use industry-proven technology with innovative approaches to provide assurance of water purity to minimise corrosion and maximise water production. Early detection of trace contamination is enabled with minimal operator supervision.
Using the 2300Na and 2800Si analysers for ultrapure water monitoring at sub-ppb levels, ensures the highest quality water is delivered. Any sodium or silica breakthrough of a polisher cation/anion resin is immediately detected at sub-ppb levels and contaminated water can be diverted before it reaches critical areas. These on-line analysers are ideal for pure water treatment cation/anion exchange monitoring, power steam quality monitoring and power condensate polisher monitoring.
