Mol
Realization of amount of substance through MiC involves the determination of accurate amounts of reactants, reagents and products in a chemical reaction by use of definitive methods such as Gravimetry, Titrimetry, Coulometry and pH by Harned Cell primary method etc.
Impact
The realization of base unit ‘mol’ through MiC will have impacts on Food quality and security, Energy, Environment & Health, Societal, national and international Trade & Indian economy, through quality system of MiC in the country.
MiC
Broad Areas are…
organic/ inorganic/ gas/ electrochemical/ surface/ and bio analysis etc..
Possible Areas for MiC & CRMs
Gas
Stable gas, Reactive gas and Multi-component gas mixures
OrganicClinical, Medicine, Environment, Forensic & Doping, Petroleum, Agriculture & Food and others
InorganicElemental, Geochemical, Soil, Metal & Alloys, Environmental, Bldg. Materials, Health, Agriculture and others
