    National Metrology Institute of Malaysia (NMIM) is established to support the industries and nation’s needs on the reliability of measurement unit in Malaysia. Its existence has evolved from a local calibration organization to positioning itself as standard laboratory which is recognized internationally.

  • calibration services
    Calibration plays an important role to ensure the accuracy of a measurement and quality control. It is essential to guarantee quality of products is at best due to competitiveness of various sectors arises nowadays. In addition to that, the science of measurement is crucial in economic development, social well- being, safety and health as well as public welfare. 
    NMIM functions as reference standard laboratory that provides traceability to the SI unit for mass (weight), length, time, resistance, voltage and density.

    The Mutual Recognition Arrangement of International Committee for Weights and Measures (CIPM MRA) is the supporting structure through the National Metrology Institutes (NMIs) in corroborate the international equivalence of their measurement standards and the calibration and measurement certificates issued by them. The technical basis of CIPM MRA is the set of results obtained for certain range of time through scientific key comparison carried out by the Consultative Committees (CCs) of the CIPM, the International Bureau of Weights and Measures (BIPM) and the Regional Metrology Organizations (RMOs).

Structure Elucidation

hpos1STRUCTURE ELUCIDATION OF ORGANIC SUBSTANCE USING NMR SPECTROSCOPY

The chemical structure of an organic compound can be determined by NMR spectroscopy. Different atoms within a molecule resonate at different frequencies at a given field strength. The observation of the resonance frequencies of a molecule allows us discover structural information about the molecule. The structural elucidation based on intensive 1D and 2D NMR techniques.
