[Reference materials for quality control of water analysis].
The ability to carry out analytical determinations meeting the needs which have prompted them is the first priority of a laboratory independent of its specific area of competence. In this framework the key concepts inspiring the quality management of a laboratory are discussed with particular emphasis on the quantification of analytes in water, the availability to this end of certified and work reference materials, their use for the quality control of measurements and the participation in proficiency testing for quality assurance and sampling procedures. A laboratory managed in conformity with such criteria allows analytical methods to be validated and generates valid, defensible and comparable experimental information on the qualitative and quantitative presence of organic and inorganic substances in water.
