Abstract

A reference material for the determination of low oxygen contents in copper (CRM 054R) has been prepared to replace the exhausted CRM 054. The homogeneity of the material is demonstrated. The oxygen content has been determined by charged particle activation analysis and confirmed by fusion extraction techniques. The mass fraction of oxygen is certified as (0.47 +-0.04)microg/g.
