UME
Gas Metrology Laboratory
About Us
The main objective of the field of Gas Metrology is to develop, study and apply the necessary methods for the identification and measurement of energy and industrial gases, vehicle exhaust gases and gas components in the atmosphere, and to establish a high quality traceable gas measurement network. With these activities, it is aimed to carry out scientific, legal and industrial gas measurement activities accurately.
Fields of Activity
Low uncertainty gas standards prepared within the scope of gas metrology serve to ensure and maintain traceability in measurements needed in health, environment and safety issues. In the Gas Metrology Laboratory, the necessary activities are carried out to establish a traceability chain in gas measurements in our country and to ensure traceable and reliable gas measurements, primary gas standards are prepared and project activities are carried out. Cooperation is established with relevant institutions and organizations to meet national and international needs in scientific, legal and industrial fields in the field of gas metrology.

Projects and Collaborations
In this project, the preparation and certification of primary reference gas mixtures in all concentration ranges for carbon monoxide and carbon dioxide gases, which play an important role in air quality measurements, are planned. At the end of the project, these gas mixtures will be prepared and reference material preparation and analysis services for these gases will start to be provided. Also with this project; In the 2013 EMRP project "SRT-v04 Metrology for high-impact greenhouse gases", the activities in the work packages in which the Gas Metrology Laboratory is involved will be realized, With the preparation of primary reference gas mixtures, which is the primary task of the Gas Metrology Laboratory, the traceability of the calibration gases required by public and private organizations related to the measurements of air quality and the mixtures prepared by private gas producers will be ensured through TÜBİTAK UME, and finally, it will serve to meet the demands of the national metrology institutes of other countries regarding the preparation of primary gas mixtures or the establishment of the relevant infrastructure.

In this project, it is planned to prepare and certify primary reference gas mixtures at various concentration ranges for component gases (methane, ethane, propane, i-butane, n-butane, i-pentane, n-pentane, hexane, hydrogen, helium, carbon dioxide and nitrogen) which have an important place in natural gas measurements. At the end of the project, approximately 15 primary gas mixtures will be prepared and reference material preparation and analysis services will be provided for these gases. In addition, this project i) to participate in the comparisons related to natural gas analyses included in the comparison list planned to be organized by BIPM GAWG between 2013-2023, ii) to ensure the traceability of private gas producers, distribution companies and private or public laboratories performing gas analysis through TÜBİTAK UME with the preparation of primary reference gas mixtures, which is the primary task of the Gas Metrology Laboratory, and iii) to meet the demands of other country national metrology institutes, which are newly established or to be established, regarding the preparation of primary gas mixtures or the establishment of the relevant infrastructure.

In this project, the design and manufacturing of reference gas calorimeters in accordance with ISO 15971:2008 'Natural Gas - Properties of Measurement - Calorific Ratio and Wobbe Index' standard, solid and liquid reference calorimeters in accordance with TS 1740 2006 'Liquid Hydrocarbon Fuels - Determination of Heat of Combustion - Calorimeter Bomb Method' and ASTM D5865-2013 'Test Methods for Thermal Values of Coke and Coal' standards will be realized.
The construction of all three reference calorimeters is based on the same principle. While the combustion chambers of the solid and liquid calorimeters are made of stainless steel material and their interior parts need to be polished, the combustion chamber of the reference gas calorimeter is made of glass. With these reference calorimeters, the amount of heat energy generated by the combustion of solid, liquid and gaseous fuels can be measured at the international level.
Thanks to this project, the thermal values of certified reference materials with international traceability will be calculated precisely with the information obtained through experimental studies and the necessary certification procedures for the measurement of thermal values will be carried out with the calibration methods to be developed. In addition, it will pave the way for the scientific and technological studies we need on the calculation of thermal values.
