Abstract

Mass fractions of Sn and In were determined in sixteen geological reference materials including basaltic/mafic (BCR-2, BE-N, BHVO-1, BHVO-2, BIR-1, OKUM, W-2, WS-E), ultramafic (DTS-2b, MUH-1, PCC-1, UB-N) and felsic/sedimentary reference materials (AGV-2, JA-1, SdAR-M2, SdAR-H1). Extensive digestion and ion exchange separation tests were carried out in order to provide high yields (>90% for Sn, >85% for In), low total procedural blanks (similar to 1ng for Sn, <3pg for In) and low analytical uncertainties for the elements of interest in a variety of silicate sample matrices. Replicate analyses (n=2-13) of Sn-In mass fractions gave combined measurement uncertainties (2u) that were generally <3% and in agreement with literature data, where available. We present the first high-precision In data for reference materials OKUM (32.11.5ngg(-1)), DTS-2b (2.030.25ngg(-1)), MUH-1 (6.440.30ngg(-1)) and PCC-1 (3.550.35ngg(-1)) as well as the first Sn data for MUH-1 (0.057 +/- 0.010gg(-1)) and DTS-2b (0.623 +/- 0.018gg(-1)).
