Abstract:
The objective of WP2 – Advancing stable and long-lived radiogenic isotope ratio measurements of environmental pollutants was to develop robust and broadly applicable methods for the determination of isotope ratios of stable and long-lived radionuclides by mass spectrometry. The target performance was to achieve measurement uncertainties sufficiently low to resolve natural mass-dependent isotope fractionation. For the development and optimisation of these methods, the environmentally relevant elements Li, B, Cr, Cd, Ni, Sb, Pb, and U were selected as key indicators.
This report presents the state of the art and the methodological improvements achieved within the MetroPOEM project. The work focused on isotope ratio determination using a range of mass spectrometric techniques and includes i) a systematic comparison of accuracy and precision across different instrument platforms; ii) the development and optimisation of both manual and automated chemical separation procedures; and iii) the implementation of collision/reaction cell technologies to resolve spectral interferences. |
