Zusammenfassung:
This Good Practice Guide has been structured around the specific objectives and needs of the MetroPOEM project, namely to develop isotope ratio mass spectrometric methods for stable and long-lived radiogenic environmental pollutants, to produce recommendations for sample processing, treatment, uncertainty budgets, and quantification of instrumental mass bias, and the need for obtaining SI-traceable isotope amount ratios. The guide has reviewed and summarised the existing approaches to sample preparation and calibration of isotope ratio measurements. Continued progress made in evaluating and modelling instrumental isotope fractionation in ICP-based mass spectrometers, with recommendations for setting up high precision measurement protocols, are articulated in the section on correction for instrumental isotope fractionation. Separate sections on best practices for reporting results of isotope ratio measurements and constructing uncertainty budgets are also included.
The information presented should help an analyst to make an informed choice on suitable measurement strategy in the isotopic characterisation of materials. It is also anticipated that the present guide will help enhance awareness of the need for improving data comparability between different laboratories and support the community`s need for reliable isotope ratio data. |
