Nim'S Role In Developing National System Of Metrology In Chemistry For Food Analysis

The growing attention is paid to food analysis area in recent years. National Metrology Institutes have been playing the important roles in obtaining reliable, comparable and traceable analytical data. In this paper, the tasks and performances of National Institute of Metrology (NIM) China in the National System of Metrology in Chemistry (NSMiC) for food analysis are reviewed in the following aspects including: establishing the national primary standards, developing CRMs, organizing national proficiency tests, participating in CCQM comparisons and claiming Calibration Measurement Capabilities (CMCs). Finally, future perspective for the metrological underpinning to the development of food analysis is overviewed.
