  ABSTRACT: The structure of the secondary standard VET 163-1-2010 created at VNIIFTRI for the units of the dispersion parameters of suspensions is described. The secondary standard is designed to reproduce the units of particle size in suspensions over the range 0.01–5 μm and of the number density of the particles over 108–1014 cm–3. In terms of its metrological characteristics, this secondary standard corresponds to the state verification scheme for instruments for measuring the dispersion parameters of aerosols, suspensions, and powdered materials and supplements it in the section on measuring particle sizes within the nanometer range.

  ABSTRACT: A study of a metrological system for measuring the parameters of nanoparticles in natural and technological environments at VNIIFTRI is reported. It is shown that measures of the linear size of nanoparticles are needed in order to ensure the accuracy and reliability of the measurements and that suspensions of spherical latex can be used for this purpose.

  ABSTRACT: We have described and tested a procedure for measuring nanoparticle sizes in natural mineral waters, using an analyzer based on dynamic light scattering. We present the results of measurement of the particle size distribution in samples of several waters. We show that the nanoparticle size distribution is individual for each type of natural mineral water, and can be used as an identification parameter for its certification.

  ABSTRACT: Methods are considered for measuring the parameters of nanoparticles in natural and technological media as used in the nanoindustry. Exact monitoring is required for the parameters of the medium where the nanoparticles are suspended in order to obtain reliable measurement data. Measurement methods are examined for the nanoparticle size range 5–100 nm for aqueous and gaseous media in order to set up a metrological suite for measuring the parameters of nanoparticles in these media.

  ABSTRACT: The air ionic composition in a classroom was determined during the operation of a Neo Tec XJ-2100 ionizer (Germany). The amount of ions in the air was measured before and after the switch-on of the ionizer. It was shown to vary depending on the mode of operation of the device and differ from the recommended normal values. The necessity of checking up the work of air ionizers both in living quarters and at workplaces is discussed with the application of air ion counters making it possible to carry out monitoring of the air ionic composition and estimate its compliance with the sanitary and hygienic norms.
