This work presents a nine-laboratory compilation of measurements of major and trace element concentrations and their related uncertainties, unavailable in the NRC-CNRC certificate (B, Cs, Li, Ga, Ge, Hf, Nb, P, Rb, Rh, Re, S, Sc, Se, Si, Sn, Th, Ti, Tl, W, Y, Y, Zr and REEs). Measurements were mostly made using inductively coupled plasma-mass spectrometry. The results are compared with equivalent data for the last batch of the material, SLRS-5, measured simultaneously with SLRS-6 in this study. In general, very low concentrations, close to the quantification limits, were found in the new batch. The Sr isotopic ratio is also reported. specialized river water reference material ICP-MS CRM interlaboratory comparison rare earth elements trace elements 062 020 43 3 475-496 2019 1639-4488 https://www.documentation.ird.fr/hor/fdi:010076581 10.1111/ggr.12268 1639-4488 [F B010076581] https://www.documentation.ird.fr/hor/fdi:010076581 https://www.documentation.ird.fr/intranet/publi/2019/08/010076581.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-09-19 2025-02-24 fdi:010076581 fre
