Product Information

Bioactive metals, such as iron, act as important nutrients in the ocean and are often present at very low concentrations, which limit phytoplankton growth. In recent years, measurement of the dissolved stable isotope ratio of bioactive metals in seawater has provided insight into the biogeochemical cycling of these elements. Iron isotope ratios, in particular, have been shown to be useful tracers of iron sources across the open oceans.

The seaFAST Litre high-volume automated preconcentration system is designed to preconcentrate large volumes of seawater for ultratrace determination of elemental concentrations and isotope ratios.
