Stable and radiogenic heavy isotopes (e.g., Sr, Nd, Pb, U) allow fingerprinting human, geological and environmental materials (e.g., archaeological finds, food, fuels, plastics, precious metals, waste, water) and their timeline ranging from several millions to tens of thousands of years and to Anthropocene. The elemental cycles within solid Earth, hydrosphere, biosphere and atmosphere lay foundation to circular economy and carry strong societal importance, e.g. from groundwater monitoring to recycling at waste/mining sites. FINTIMS improves the national and Nordic scientific landscape by establishing a high-precision heavy isotope mass spectrometric and metal-free clean room preparation facility for low abundance isotopes. In improving the sensitivity and precision of heavy isotope analysis, new low-concentration tracer materials are becoming available and new interdisciplinary research and collaborative projects are advanced in the framework of FINTIMS throughout the society.
