✦ Synopsis
A synthetic multi-element reference material (SyRM) with a pseudo-blologlcal matnx composltlon contammg all rare earths @Es) was prepared The elemental composltlon of the SyRM was regulated by the starting materials used for the synthesis The present SyRM contains 45 elements urlth accurately known amounts and its elemental composltlon IS regulated to be closely slmdar to that of a land plant sample (NIST SRM 1572 Citrus Leaves) In order to evaluate of the rebabtity of analytical technique for REs, REs m SyRM were determmed and compared with the ongmal contents in SyRM Keywords Actwatlon analysis, Blologlcal samples, Rare earth elements, Standard reference materials
