Mettler Toledo Offers On-Line Sulfate & Chloride Analyzer for Cycle Chemistry & Makeup Water

July 2019, MARIETTA, GA ~

On-line, ppb-level chloride and sulfate monitoring:
The Mettler Toledo 3000CS Analyzer is an on-line instrument for automated measurements of chlorides and sulfates in pure water and power cycle chemistry samples. The analyzer continuously monitors these contaminants to assist in corrosion control and minimizing damage to critical power plant equipment. The 3000CS uses microfluidic capillary electrophoresis, an ionic separation technology, to directly measure trace levels of sulfate and chloride ions.
Detection Range: 0 – 500 ppb
Detection Limit: Chloride: 0.5 ppb; Sulfate: 2 ppb
Accuracy Chloride: ± 5 % of reading ± 0.5 ppb
Accuracy Sulfate: ± 5 % of reading ±1 ppb
Measurement cycle time: 45 min typical (programmable between 15 to 60 min)

Low cost of ownership compared to off-line methods
Typically, chloride and sulfate measurements are done with off-line technologies such as ion chromatography and inductively coupled plasma. These off-line systems are expensive and require additional costs for either internal or external lab work. The 3000CS sulfate and chloride analyzer allows you to reduce lab labor costs, while also eliminating the risks and expense associated with a sample being contaminated in the lab.

Easy to Maintain with ISM Predictive Diagnostics
The 3000CS features precise 2-point calibration to help ensure that your sulfate and chloride analyzer is continuously measuring within specifications. The analyzer also has Intelligent Sensor Management (ISM®) technology to provide you with diagnostics that predict when maintenance or replacement of consumables will be required.

Intuitive Touchscreen Interface
The 3000CS on-line sulfate and chloride analyzer offers an intuitive touchscreen interface, allowing operation without the need of a trained chemist, saving you time and costs. The analyzer also provides trend graphs for chloride analysis and sulfate analysis so that changes in water cycle chemistry and plant conditions can be monitored over time.

SQ144 and SQ148 Sequencers Options
Sequencers offer the capability to measure up to 8 sample streams with a sodium, silica, chloride/sulfate analyzer.

Features / Benefits

Intuitive touchscreen interface: allows display of trendlines for each measurement

Simultaneous display of ion concentrations and measurement timing: provides convenient analyzer status at a glance, saving operator time

Analog outputs with choice of scaling: enables easy integration into data acquisition systems

Convenient grab sample capability: allows measurement of additional samples or for QC checks

Full enclosure: protects reagent containers and components from plant environment

Typical Applications

Steam quality monitoring at turbine inlet to ensure chloride and sulfate levels are under acceptable limits.

Condensate monitoring at condensate polisher, to detect breakthrough or deterioration of sulfonated cation resin

Boiler feedwater monitoring, to activate boiler blowdown if needed to control contaminant levels
