Nanoparticle Surface Area Monitor 3550

SKU: 3550

This product has been discontinued as of March 31, 2018. 

The Nanoparticle Surface Area Monitor 3550 (NSAM) measures the human lung-deposited surface area of particles (reported as µm 2 /cm 3 ) corresponding to tracheobronchial (TB) and alveolar (A) regions of the lung. The NSAM 3550 provides a simple and fast solution for measuring the surface area equivalent dose in the lung. It is an important instrument for research in the fields of inhalation toxicology, health effects and epidemiology, and for measuring and monitoring workplace exposure.

Discontinued

Product Details

Occupational health risks associated with using and manufacturing nanoparticles are not clearly understood. Workers may inhale and be exposed to levels that greatly exceed ambient levels. Leading experts contend that surface area, rather than mass, should be measured for nanoparticles, because the surface area of particles and nanoparticles is greather than the surface area for the same amount of mass. This increases the chance of reaction with the body. As a result, there is a growing need to study health effects and assess workplace conditions and personal exposure to nanoparticles, based on the measurement of particle surface area.

Applications

  • Basic aerosol research
  • Inhalation toxicology
  • Industrial hygiene research
  • Health effects studies
  • Epidemiology studies
  • Occupational exposure monitoring

Features & Benefits

  • Selectable measurement modes for tracheobronchial (TB) or alveolar (A) deposition response
  • Comprehensive software for collection, storage, and display of running-average, time-weighted-average (8-hour), or total deposited surface area
  • Simple operation, fast set up and the ability to run continuously for unattended, long-term exposure monitoring
  • Sensitivity down to 10 nm
  • Over five decades of concentration, from 0 to 10,000 µm 2 /cm 3 spanning a wide range of exposure dosages
  • Data rate of one measurement per second detects short periods of high-intensity exposures
