This study presents a combined methodology of simultaneously measuring Rb–Sr/Sm–Nd or Sm–Nd/Lu–Hf isotopes in natural minerals by a means of two multiple collector inductively coupled plasma mass spectrometers (MC-ICP-MSs) connected to a 193 nm excimer laser ablation system. The ablated materials carried out of the HelEx cell by helium gas are split into two gas streams with different proportions into the Neptune for Sr (or Nd) analyses and Neptune Plus for Nd (or Hf) analyses.
