The Gas Metrology Laboratory was established in 2011. Equipment and systems available in this laboratory include the followings:

Gas Mixture Preparation Laboratory

  • Gas filling station
  • Turbo-molecular vacuum pump system
  • Cylinder roller
  • Cylinder weighing systems

Gas Analysis Laboratory

Gas Metrology Laboratory

The ultimate objective of gas metrology can be given as identification, method development for the analyses, investigation and application of industrial gases, exhaust emission gases and atmospheric gas components, as well as establishing a traceability chain for gas measurements and providing support for scientific, legal and industrial activities involving gas measurements. Primary gas standards with very low uncertainty values can provide sustainable and traceable gas measurements required in the field of health, environment and safety.
