ELGA LabWater helps investigate the history of atmospheric pollution
13 Mar 2008
Professor Carlo Barbante and his research team at the University of Venice’s Department of Environmental Sciences have been sampling Antarctic snow to look for trace levels of heavy metals. The levels of the metals, such as cadmium, lead, zinc and copper in the snow are very low, on the order of pg/g, so the purity of the samples is of critical importance.
The low concentration of heavy metals in the samples necessitates the use of ultra-pure water, and this Technology Note explains the use of the ELGA LabWater PURELAB Ultra Analytic system in the group's ICP-SFMS experiments.
