Interlaboratory Comparison on the Determination of Trace Elements and Rare Earth Element Mass Fractions in Marine Sediment Sample IAEA-MESL-2024-ILC-TE-SEDIMENT

Interlaboratory comparisons (ILCs) involve comparing participants’ results with an assigned value, which is typically derived as a consensus value from the overall set of results obtained. These exercises are designed not only to monitor the measurement performance and analytical capabilities of laboratories, but also to identify existing gaps and problem areas where further development is needed. Regular participation in ILCs enhances confidence in the results produced and the methodologies applied, and provides objective evidence for accreditation purposes. This publication summarizes the results of the MESL-2024-ILC-TE-SEDIMENT interlaboratory comparison on the determination of trace elements and REEs in a sediment sample.
