Our uraniferous phosphatic sandstone replacement certified reference material is now available. AMIS0055 replaces AMIS0054 which proved very popular as a phosphate standard, butwhich is now depleted. Both materials were supplied by Uramin from the Bakouma Project in the Central African Republic. AMIS0055 has been certified for 10 economic and trace elements (below), and for an additional 10 major elements.
