Analytical tapes and filters

Filtering analytical tapes NEL3, Nel-4LFS-2 strip of a filtering material with consolidated edges of 25 or 50 mm in width and up to 50 m in length. Intended for a sampling of aerosols, including radioactive ones, with rigid particles for the measurement of quantity, properties and structure of the trapped disperse-phase in the continuously operational devices.

Sorption and filtering tapes SFL-2I-50, SFL-2R-50 contain highly disperse hemosorbent and are intended, depending on a type of a sorbent, for a sampling of aerosols and steams of iodum with the subsequent measurement by radiometric devices, or for a sampling of aerosols and steams of mercury with the subsequent measurement of the contents of mercury.

Analytical aerosol filters AFA are used for analysis and control of aerosols:

  • Radioactive, toxic and bacterial in the air of a working area of industrial premises, in the near-the-ground atmospheric layer;
  • Radioactive, toxic and bacterial, present in ventilation and technological air (gas) flows;
  • For the monitoring of the efficiency of gas purification devices, both personal and collective protection facilities against aerosols;
  • In R&D works in the field of aerodispersible systems.

Sorption-filtering iodic analytical filters AFAS-I-20, AFAS-I-10, AFAS-I-20 are made of FPP material with high-dispersity sorbent, and intended for the sampling of aerosols and vapours of iodine and the subsequent measurement of the detained deposit by radiometric devices.

Fuel grade indicators are intended for express analysis of aviation fuel for the presence of water and mechanical impurities within the limits of a mass share of water 0.001-0.003% and impurities 0.0002-0.0003%.
