This European Standard specifies performance criteria for the selection of methods of analysis of trace elements in foodstuffs. It provides general considerations about the special requirements on sample preparation, apparatus, equipment and reagents for trace elements analysis. In selecting a method of analysis for a specific food matrix, the analyst should give preference to any method which has been developed by the appropriate vertical Technical Committee rather than using a method which has been developed by the horizontal Technical Committee CEN/TC 275/WG 10. However it is the responsibility of the analyst to determine whether an applicable vertical standard has been published.
