    The new certified reference material of chlorobenzene as a means of providing the metrological traceability for calibration and measurements by I. Y. Tkachenko, A. G. Budko, A. Y. Mikheeva, A. I. Krylov

    Published 2020-06-01
    “…The article is devoted to the development of a reference material of chlorobenzene composition, providing metrological traceability of measurement results to the State primary measurement standard of units of mass (molar) fraction and mass (molar) concentration of organic components in liquid and solid substances and materials based on liquid and gas chromatography-mass spectrometry with isotopic dilution and gravimetry GET 208-2014.The paper considers an indirect method for determining the purity of the starting substance, describes the main stages of development of the reference material, and presents the results of the evaluation of the reference material metrological characteristics, including studies on homogeneity and stability.The reference material of the composition of chlorobenzene has the following metrological characteristics: mass fraction of chlorobenzene (from 993.0 to 999.8 mg/g); molar fraction of chlorobenzene (from 99.30% to 99.98%); the expanded uncertainty of the certified characteristics is 0.02% (at k = 2).The reference material ensures metrological traceability to units of measuring instruments and measurement results, and is intended for verification, and calibration and graduations.…”
