This analytical system is used for analysis of stable isotopic ratios of not only natural samples but also farm and marine products and artificial materials. It has been applied for studies on geochemistry covering solid-state materials (i.e. rocks and minerals). In RIHN, it is applied for studies on various environmental samples including water, atmospheric fallout, soil, living things, farm and marine products, food, biological minerals (e.g. bones and teeth), archeaological materials, etc.
Using this analytical system, stable isotopic ratios of Sr, Pb, and Nd in environmental samples are mainly analyzed. It is the most advanced analytical instrument applied for studies on identification of sources of environmental materials, an assesment of environmental impact, environmental restoration, etc.
