The stability of geochemical reference materials is subject to breakdown due to mineralic component or particle size fraction segregation or to ambient oxidation. A statistical design is presented to the analyst for detecting such a breakdown as soon as possible to avoid the resultant degradation in his output. The application of this design to a base metal certified reference material, MP‐1a, is illustrated.
