On-line water chemistry analysers

Efficient and reliable monitoring of low concentrations of various impurities in pure water treatment is critical for microelectronics and power cycle chemistry applications. Mettler Toledo Thornton offers a range of sodium, silica and chloride/sulphate analysers that use industry-proven technology for pure and ultrapure water monitoring at sub-ppb levels to ensure the highest quality water is delivered. Early detection of trace contamination is enabled with minimal operator supervision.

Detection of trace sodium contamination

Thornton’s sodium analysers are on-line measurement instruments designed for continuous monitoring of sodium levels in pure and ultrapure water and power cycle chemistry. On-line sodium analysers offer measurements at sub-ppb levels to provide immediate detection and diversion of sodium contamination before it reaches critical areas. With self-calibration capabilities and a fully protective design, this sodium analyser ensures safe, reliable and continuous operation.

Silica monitoring for water purity

Silica analysers provide critical on-line measurements for ensuring water purity in power cycle chemistry and in ultrapure water monitoring. The range of silica analysers offers a compact design to deliver fast, reliable and effective multistream sub-ppb silica measurements. Maximise uptime and achieve superior performance with this analyser with intelligent diagnostics to provide early detection of trace silica levels in your water stream.

Chloride and sulphate detection

Chloride and sulfate analysers are on-line devices for continuous ppb-level monitoring of chloride and sulfate in a water system. The combined chloride and sulfate analyser uses microfluidic capillary electrophoresis, an ionic separation technology, to directly measure trace levels of harmful sulphate and chloride ions. With on-line measurements every 45 minutes, the analyser automatically performs direct chloride and sulphate measurements in the water/steam cycle, allowing immediate detection of sample contamination. The most important point in the cycle is at the turbine inlet, to ensure that only acceptable levels of chlorides and sulphates enter with the steam into the turbine.
