Abstract: | The system for Metrology in Chemistry in Germany is described. At the national standards level, a network of high-level chemistry
institutes coordinated by the national metrology institute, PTB, provides the primary references for chemical measurements.
A dissemination mechanism employs chemical calibration laboratories accredited within the framework of the German Calibration
Service (DKD). They act as “multipliers” between the national standards level and the user level by providing the user with
calibration means which are traceable to the SI via national standards. Traceability structures in clinical chemistry, electrochemistry,
elemental analysis and gas analysis are described |
