This unique resource presents members of Association Internationale. The sediment materials were air-dried, sieved, homogenized, packaged in glass bottles (60 g each), and radiation sterilized. Certification of these CRM for trace elements was conducted by NMIJ, where each element was determined by at least two independent analytical by:   As REEs (and other trace element concentrations) are vastly different in different types of geological materials, it is advisable to select a standard similar in composition to the samples, for example, a standard granite for the analysis of granites or a standard ultramafic rock for the analysis Cited by: 3.

We have investigated the performance of a combined single-collector sector-field ICP-MS and a new solid-state nm Nd:YAG laser ablation system for trace element analysis of geological glasses. Experiments were made with certified MPI-DING, USGS and NIST reference glasses.
