Mettler-Toldedo Thornton 3000CS chloride and sulfate analyser

Mettler-Toledo Process Analytics is launching an online instrument for direct measurement of corrosive ions found in power plant water and steam.

Chlorides and sulfates cause pitting and stress corrosion in expensive power plant components such as turbines and boilers, leading to extensive maintenance and unplanned shutdowns. Monitoring these ions at low ppb levels has therefore been identified as key measurements in power plant chemistry.

The Mettler-Toledo Thornton 3000CS analyser provides online, trace-level chloride and sulfate measurements for corrosion control every 45 min. The 3000CS uses microfluidic capillary electrophoresis, an ionic separation technology, to provide an alternative to expensive offline methods such as ion chromatography and inductively coupled plasma.

The unit features semiautomatic calibration and an intuitive touchscreen interface, allowing operation without the need for extensive training. Mettler-Toledo’s Intelligent Sensor Management technology in the analyser provides diagnostics that predict when maintenance or replacement of consumables will be required.
