Four incompatible elements of great geochemical interest were determined concomitantly using a new procedure, combining sample decomposition with a LiBO 2 flux and the isotope dilution method. Prior to mass spectrometric measurements with a plasma source quadrupole‐based instrument, the analytes were isolated from matrix elements with high recovery, using a new separation scheme involving a small column comprising the extraction chromatography material, U‐TEVA.Spec. After a detailed description of the experimental procedure, the potential of this method is demonstrated by triplicate analyses of four international reference materials (DNC‐1, W‐2, JA‐1, RGM‐1) spanning a range of analyte concentrations and representative of various silicate rock bulk compositions.
