Modern Water Dual Cell OVA7100 On-Line Metal Analyser - Carbon/Carbon Electrodes - IK-710-000DCC-01

IK-710-000DCC-01 Dual Cell OVA7100 On-Line Metal Analyser - Carbon/Carbon Electrodes by Modern Water

Measuring trace metals in water streams, whether its drinking water, ground water, river water, factory effluent, soil washings or WWTP discharge is a vital part of modern environmental monitoring. Voltammetry offers an internationally accepted alternative to laboratory analysis or automatic samplers. Modern Water's range of OVA products are cost effective, accurate, simple to use and easy to integrate into existing systems.

• Can be configured to monitor 23 different metals
• Very low detection levels (down to 0.1 μg/L*)
• High levels of accuracy and repeatability – Excellent Correlation with Laboratory Methods (AAS, ICP-MS)
• 24-hour monitoring at high frequency can identify and isolate events that daily average sampling may miss
• Short analysis times allow identification of events as they occur – laboratory analysis typically identifies an event only after it occurred
• Dual-cell option can measure up to 10 metals
• Programmable alarm and outputs for out-of-range samples or system faults.
• Remote access and data communication with many different secure communication options available including wireless
• Easy connection to process control room allows integration into automated plant control systems (dosing, flow diversion).
• Pre-treatment options available to eliminate interferences and allow total and dissolved concentrations to be monitored
• Solid electrodes-no hazardous mercury drop electrodes
• Automated testing of pump operation and reagent/ sample supply
• Standard addition or multiple point calibration curve options
• Multiple language interface options - including traditional and simplified Chinese
• Online technical support (requires internet connection)

Process explained

In Voltammetry metals are drawn onto the working electrode when a specific voltage is applied to the water sample under test.

When a stripping voltage is applied, the metals return to the sample solution, generating a small current. Each metal has a specific voltage at which it returns to solution. So the metal is identified by its stripping voltage and the current generated indicates the concentration of metal in the sample.

What it detects

• The OVA7100 can detect a range of metals (for example: As, Cd, Cr, Cu, Hg, Ni, Pb, Se, Tl, Zn, and others) to single figure μg/l levels (typically 0.5-5μg/l).
• Colour or turbidity does not affect the method. Samples range from waste water, process water, river water to drinking water.
• Acid/ UV digest and filtration are treatment options.

Applications

• Accidental or deliberate contamination events
• Drinking water intake and distribution
• Groundwater monitoring /natural attenuation
• Industrial effluent monitoring
• Mining and metals processing
• Monitoring of rivers, lakes, reservoirs, seawater
• Wastewater recycling and WWTP influent monitoring
