The IV International Scientific and Technical Conference “Metrology on Physicochemical Measurements” was held 17-19 September 2019 in Suzdal, Russia. It was organized by the All-Russian Scientific Research Institute of Physicotechnical and Radio Engineering Measurements (VNIIFTRI) with participation of the Cooperation on International Traceability in Analytical Chemistry (CITAC) under the slogan “Let’s speak about measurement uncertainty”.
About 100 participants from metrological, academic and high-education institutes, metrology service centers and other organizations of Belarus, Bulgaria, China, Israel, Germany, Switzerland and Russia took part in the Conference. There were 44 oral presentations, some posters and a small exhibition.
The Conference program included scientific and technical topics from the fields of electrochemistry, spectrometry, chromatography and other instrumental methods of physicochemical analysis; reference materials; measurements of dispersed parameters of particles in heterogeneous media, including aerosols and suspensions and air ions; applied and legal metrology and others.
During the framework of the Conference, interesting suggestions were made to further improve the level and quality of the metrological work performed, current problems in the field of ensuring the uniformity of measurements were highlighted, the opportunity to exchange experiences, establish contacts between organizations was provided. New achievements in the field of fundamental and applied research in the field of metrological support of physico-chemical measurements, world and domestic achievements in the development of measuring equipment in this field are presented.
After welcoming remarks by Prof.Dr.Sergey Donchenko, General Director of VNIIFTRI (Russia), such well-known scientists as Prof.Dr.Alfred Wiedensohler, Head of Experimental Aerosol and Cloud Microphysics Department (Leibniz Institute for Tropospheric Research, Germany); Dr. Samuel Wunderli, CEO “atomolmetron” GmbH, Independent Consultant on Metrology, CITAC member (Switzerland); Dr. Ilya Kuselman, Independent Consultant on Metrology, Editor of CITAC News and Chair of the IUPAC Interdivisional Working Party for Harmonization of Metrology and Quality Guidelines (Israel); Dr. Anatoly Trubitsyn, Scientific Advisor of Gorniy TsOT Ltd. (Russia); Dr. Natalia Muravskaya, Head of QM, VNIIOFI, Chair of COOMET TC 3.1”Quality Forum” (Russia); Dr. Anastasia Semenova, Deputy director of the Institute of Food Systems after Gorbatov (Russia) and e.g., as well as many young scientists took part in the conference with reports. In total, more than 40 reports were presented at the conference, of which 16 reports were made by scientists of VNIIFTRI. The conference was very active, heated discussions continued during the breaks.
The participants were satisfied by the scientific level and usefulness of the Conference.
The next such conference is planned by VNIIFTRI for 14-16 September 2021 in beautiful historical place - Park-Hotel “MOROZOVKA”, Moscow region, Mendeleevo, Russia.
