The preparation of formaldehyde gas mixtures required for metrological assurance of air pollution control is an urgent task. Methods for the preparation of gas mixtures of formaldehyde for metrological purposes are considered. The 2 μmol/mol-level gas mixtures of formaldehyde in nitrogen have been obtained by a dynamic-gravimetric method with the depolymerization of trioxane vapor. The efficiency of the trioxane conversion process was experimentally studied. The sources of uncertainty are analyzed in detail. The reference gas mixtures obtained were used for the formaldehyde mole fraction measurements during the CCQM-K90 key comparison. The relative expanded uncertainty of the measurement U = 3.3% was achieved, confi rmed by the comparison results.

The development of a new type of reference standard for carbon isotopic composition consisting of 12CO2 + 13CO2 and N2 gaseous mixtures in tanks under pressure is discussed. These standards are required for measuring the isotope ratio 13C/12C in gaseous mixtures of CO2. The procedures for preparing and verifying the reference standards are described and their stability is tested. These standard samples can be used for calibrating (testing) isotopic infrared analyzers and mass spectrometers.

The main issues and recent achievements in the field of metrological assurance of carbon isotope-ratio analysis are considered. An overview of the existing methods of carbon isotope-ratio analysis of gaseous, liquid, and solid substances is offered. Recommendations for the development of new carbon isotopic reference gaseous mixtures in vessels under pressure traceable to the international standard VPDB are given. The basic error limits required for their certification are formulated.

The basic principles of development of metrological assurance of quality control of products on the basis of two-phase hydrocarbon systems (stable and unstable gas condensates) are considered.

Measurement assurance in the identification of ozone-depleting substances is considered. It is indicated thatozone-depleting halogenated hydrocarbons must be monitored, and portable devices for detecting counterfeits in customs border control are needed.

The management of the production of calibration specimens (of approved type and enterprise-wide) of a composition of hydrocarbon mixtures is considered; special attention is paid to the traceability of the standards to GET 154–2011, the state primary standard of the unit of mole fraction and unit of mass concentration of components in gaseous media.

A metrological complex is developed for provision of measurement unification during production of carbon nanomaterials, i.e., fullerenes, including measurement chromatographic and mass-spectrometric equipment, a set of procedures for certifying reference standards and state standard specimens, and technological regulations for preparing high-purity fullerenes C60 and C70.

The organizational principles of the international system of uniformity of analytic chemical measurements implemented by the International Bureau of Weights and Measures and the Consultative Committee on Quantity of a Material – Metrology in Chemistry are described. The degree of participation of Russian metrological institutes in the implementation of the international agreement on mutual recognition of national standards and calibration certificates is considered. An estimate of the level of measurement and calibration capabilities of Russian metrological institutes is presented.

A complex of studies on the development of a system of metrological assurance of measurement technologies in the recovery, transportation, and delivery of gas to customers in the Russian Federation is considered. A system of metrological assurance for quality control of natural gas developed at the Gazprom company that supports the traceability of the results of measurements to the state primary standard of units of mole fraction and mass concentration of the components in gaseous media (GET 154-01) and renders the results of quality control of natural gas internationally recognizable is presented.

Results are provided for pilot comparisons between the Mendeleev All-Russia Research Institute of Metrology (VNIIM) and the All-Russia Research Institute of Physicotechnical and Radio Measurements (VNIIFTRI) in the field of particle size measurement within the framework of COOMET Project No. 378/RU/06. The research area is spherical particles with an average diameter in the range 0.5–1.5 μm. Measurements are performed by optical and electron microscopy, and a diffraction method.

Methods and instruments for ensuring unity of measurements of the ozone content in the surface layer of the atmosphere are described. The uncertainty budget of the standard photometric system based on an SRP-type photometer, forming part of the State Primary Standard of the units of molar fraction and mass concentration of the components in gaseous media (GET 154-01) is presented. The results of international key comparisons carried out under the aegis of the BIPM are presented.

A requirement is substantiated for improving the accuracy of certification for gravimetric standard gas mixtures (GSGM). Principles are developed for external quality control of GSGM for working standards of the zero order with application of statistical monitoring methods for quality according to a quantified characteristic.
