Abstract

Certified Reference Materials and Proficiency Testing Schemes are essential tools to ensure the quality of analyses of “field” chemical laboratories. LNE, the French National Metrology Institute has participated in a proficiency test, organized by BIPEA, on the determination of mercury and selenium in drinking water to guarantee the traceability of laboratory measurement to the SI unit. This new cooperation between NMI and PT providers allows to establish new traceability schemes for chemical analyses.
