SI file, column chemistry and mass spectrometry details (ABF decomposition)

The data are related to an ammonium-bifluoride-based rock digestion procedure. Table S1/S2 describe ion exchange chemistry procedures for hafnium, strontium and neodymium separations and purifications using micro-columns filled with AG-50W-X8 (Sr) and Ln (Hf-Nd) resins. Table S4/S4 provide information on a procedure of amplifier gain calibrations using a combination of 10(13) Ohm amplifiers for masses 172-176, as applied on the JMC-475 hafnium isotopic standard, and calculated gain factors for each measurement cycle. Table S5 lists data of calculated blank contributions for 5 USGS geological rock reference materials (GRMs), including AGV-2, BCR-2, GSP-2, RGM-2 and STM-2, based on measured total chemistry blanks and elemental concentrations of the GRMs.
