Water Testing

A new ultra-sensitive, low-cost and portable system for detecting mercury in environmental water has been developed by University of Adelaide researchers.

A group of McMaster University researchers has solved the problem of cumbersome, expensive and painfully slow water-testing by turning the process upside-down.

Researchers from North Carolina State University have developed a new technique that uses existing technology to allow researchers and natural resource managers to collect significantly more information on water quality to better inform policy decisions.

With its new 875 Karl Fischer Gas Analyzer, Metrohm combines decades of experience in moisture analysis and sample handling. The KF Gas Analyzer is designed to handle nearly any gas sample - compresses, liquefied or native. It is fully equipped to measure the absolute moisture content of LPG, petrochemical intermediates, natural gas or other compresses or liquefied gases.


Matthew Sullivan, an environmental specialist in the Field Operations section of the Bureau of Environmental Services for the city of Portland, Oregon, talks to contributing editor Tanuja Koppal, Ph.D., about how field testing, particularly for water analysis, has changed over the years. The testing equipment is now better suited for field analysis, in terms of its size, compactness, and robustness. The newer instruments have also allowed for sampling and testing to be done remotely and in an automated fashion. Overall, field instrumentation is striving to provide faster, cheaper, more robust, and more real-time measurements for routine analysis.
