Abstract

The transformation of a batch of approximately 80 kg wet Antarctic coastal marine sediment, collected in the Terra Nova Bay during the eleventh Italian expedition to the Antarctic, into a sampled, dry and conservable powder to be certified for the content of elements such as Al, As, Ca, Co, Cr, Cu, Fe, Mn, Ni, Zn, Hg, Pb was carried out at IRMM's Reference Materials Unit. The material was transformed in stable, homogeneous dry powder by sieving and drying, jet-milling, turbula mixing and subsequent sampling using a non-metallic sample divider. The quality of the materials was verified by particle size measurements, Karl-Fischer titration, and solid sampling Zeeman atomic absorption.
