Chemical compositions of international reference materials (basalts BHVO-2 and BCR-2) analysed as quality control standards

Further details and definitions:* BHVO-2. : Basalt Hawaiian Volcanic Observatory 2* BCR-2 : Basalt Columbia River 2* n : number of analysis replicate* Method: HF-HNO3 acid digestion followed by elemental composition measured on an Agilent 7900 quadrupole ICP-MS instrument with 2.5% HNO3 as eluent.* Information about the table : Measured and recommended reference concentrations (Jochum et al., 2016) agree within ±10 %, except for samples and elements (Cs, Tl, Pb and Bi in BHVO-2 and Zn in BCR-2).
