New Online Trace Metals Analysers

Instrumentation specialist Cogent Environmental (UK) has launched a new advanced trace metals analyser that Managing Director Chris Welsh says "will offer enormous advantages over laboratory analysis."

The new OVA7000 can be configured to provide continuous monitoring data for a wide range of analytes (total As, Au, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Tl, U, Zn) in surface water, industrial wastewater and process water. With 20 years of experience in the development of online metal analysers, Chris says, "The Cogent engineers have designed the new OVA7000 to offer the advantages of continuous data to those that might traditionally have chosen laboratory analysis."

Laboratory instruments are capable of producing extremely high levels of precision, but Chris believes that the advantages of continuous data far outweigh the high levels of accuracy that are often unnecessary in practical situations. "Real-time data provides an opportunity for immediate response to spikes in the data, which would often be missed by laboratory spot checks." He says.

The OVA7000 has also been designed for flexibility. Operating from DC power, the analyser is ideal for remote sites and offers both wired and wireless communications. A key feature of the instrument is the automatic pre-treatment that has been incorporated into the design to ensure accuracy and reliability.

The new instrument features a novel Copper reduction system which is very important to ensure accuracy and reliability. The health effects of Arsenic levels in drinking water are a particular concern in countries for which groundwater levels are high and Chris Welsh anticipates a high level of demand for this instrument because of the benefits of continuous data.
