gm1Gas Analysis

Gas Analysis Laboratory is equipped with Gas Chromatograph with various type of  detectors; for example GC-FID, GC-TCD, GC-SCD, GC-ECD, GC-MS and GC-PDHID, which is an ideal tool to analyse gas samples and enabling our end users to determine the amount of different gaseous in a gas mixture.

Structure Elucidation


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.

Elemental Measurement

em1Elemental Analysis using

Energy Dispersive X-ray Fluorescence (EDXRF)

X-ray fluorescence (XRF) spectrometry provides an accurate and high precision quantitative for determination of ‘total’

‘total’ inorganic elements in solid samples such as soils, sediments, mining ores, dusts, consumer products (including paint, plastics, pharmaceuticals, cosmetics, electronic components and toys), metals and alloys (including jewellery). 

  NMIM offers a comprehensive suite of analysis from Sodium (Na) to Uranium (U) with sensitivity from <1 ppm up to 100 % by utilization of EDXRF.

Trend of elemental analysis techniques

em3Purity Assessment of Precious  Metal

EDXRF is an alternative method for analysis of precious metals.  It is a nondestructive technique and therefore used for applications where there is a need to maintain the  integrity of a sample. 


em4Analysis of Hazardous Substances and Products for WEEE/RoHS Compliance by EDXRF

EDXRF has emerged as the primary method for screening products for Restriction of Hazardous Substances and Waste Electrical and Electronic Equipment (RoHS/WEEE) compliance. 

High Purity Organic Substance

Quantitative Nuclear Magnetic Resonance (qNMR) has been developed for the determination of high purity organic compound. The qNMR is a fast and non-destructive method that has the advantage in determining purity by principal component analysis.

       NMR Spectroscopy



NMIM plays an important role in disseminating the traceability of measurement to the whole country based on the International System of Units. Just like other world standard laboratories, NMIM has great responsibility in ensuring the national metrology infrastructures meet and comply with the global measurement standards.
