Certified reference materials for leaching procedures



It is therefore of primary interest to have samples specified for a well described procedure  in order to compare different methodologies.


CRMs play a major role in the development and validation of methods and for quality control. The following certified reference materials (CRMs) are available for the fractionation of different elements from solid materials:
