The A*STAR’s National Metrology Centre (NMC) is the national measurement institute of Singapore, dedicated to advancing measurement science for an innovative and competitive economy
NMC establishes, develops, maintains and disseminates the national measurement standards traceable to the International System of Units, providing key support to a wide spectrum of industry.
Achieving the nation’s highest level of physical measurement through close collaboration with leading national and international organisation.
With a multidisciplinary team of experienced scientists and engineers and state-of-the-art facilities, NMC provides dedicated services to industry partners to meet their specific needs.
NMC believes in working in close collaboration with industry partners, to create values for them and fuel growth for the industry.
NMC provides calibration of various gas analysers and gas sensors using our primary reference gas mixtures. We also produce Certified Reference Mixtures (CRMs). These CRMs are prepared gravimetrically in accordance with ISO 6142 and are validated against in-house Primary Standard Gas Mixtures (PSMs).
Vehicle Exhaust Control
Ship Emission Gas
IMO (International Maritime Organization) requires the reduction of the combinations of sulphur oxide (SOx), carbon dioxide (CO2) and nitrogen oxide (NOx) from shipping and floating vessels be less than 0.1% by 2015. To reduce sulphur dioxide (SO2) emissions, ships could possibly use Exhaust Gas treatment systems such as a sulphur dioxide scrubber system. For the assurance of compliance and traceability, accurate measurement and calibration of SO2 detectors need traceable certified reference gas mixture. NMC’s gas laboratory is able to provide following gas standard to help the maritime industry to comply with IMO regulation on gas emission.
Volatile organic compounds (VOCs)
NMC is developing natural gas standards which can be used to calibrate natural gas analysers. Composition of natural gases need to be determined with high accuracy to have accurate calculation of the calorific value. Composition measurement will cover C1 to C10 components. Accurate measurement of the heavy hydrocarbon components is useful to determine hydrocarbon dew point with high accuracy, which is important to avoid condensation of the gas mixture during transportation via the gas pipeline.
NMC has established the first primary ozone measurement facility in South-East Asia based on Standard Reference Photometer (SRP 46) and has capabilities for the calibration of ozone analyzers in the range of 0 to 500 nmol/mol.
