A novel combination of the technique of diffusive gradients in thin films (DGT) and laser ablation high-resolution multicollector inductively coupled plasma mass spectrometry was developed to study sulphur isotope variations of dissolved pore-water sulphide in freshwater and marine sediments. The technique enables two-dimensional mapping of isotopic variations (δ 34 S) in dissolved sulphide...
Precise and accurate measurements of 186 Os/ 188 Os and 184 Os/ 188 Os ratios are a key requirement in the search for evidence of interaction between the Earth's core and mantle [e.g., Brandon, A.D., Walker, R.J., 2005. The debate over core–mantle interaction. Earth Planet. Sci. Lett. 232, 211–225] and in understanding nucleosynthetic processes, in particular the P-process,...
