Description
Summary:Global decisions made on the basis of chemical analytical results need global comparability. The concept of traceability is important and necessary but not sufficient to achieve global comparability, especially for routine analysis in environmental protection, health care and public safety. Sometimes comparability is only determined by the method. In this case validated methods have to be known and recognized internationally. In addition, a minimum level of proficiency of the personnel producing analytical results has to be guaranteed. Finally, a system of measures designed to build up trust is needed for worldwide acceptance of analytical results. The method of self-declaration by the supplier of chemical analytical services has the advantage of presenting specific responsibility and gaining a good reputation. Additional methods should be employed. The evaluation of reference materials by specific quality criteria is mentioned as an example.
