Abstract
This article presents the description, metrological characteristics and application of State primary standards developed at the All-Russian Research Institute of Physicol-Technical and Radio-Technical Measurements (VNIIFTRI). These include the state primary standards for pH and pX in aqueous solutions, units of the dispersed parameters of aerosols, suspensions and powdery materials, units of the mass fraction and mass (molar) concentration of inorganic components in aqueous solutions based on gravimetric and spectral methods of analysis. In addition, the article discusses R&D projects that are currently being realized at VNIIFTRI, including the production of standard-titres and buffer solutions for pH-metry, as well as working standards for assessing the activity of Na+, K+, F-, Cl-, Br-, I-, NO3-(pX) ions in aqueous media.
