Preparation and production control of certified reference material of Antarctic Sediment
The transformation of a batch of ca 80kg wet Antarctic Coastal Marine Sediment, collected in the Terra Nova Bay during the 11th Italian Expedition to the Antarctic, into a samples, dry and conservable powder to be certified for the content of elements such as Al, As, Ca, Cr, Cu, Fe, Mn, Ni, Zn, Hg, Pb was carried out at IRMMÆs 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 on hand of particle size measurements, Karl-Fischer titration, and solid sampling Zeeman atomic absorption.
