Project Scope

  • Task 1. Optimization of the magnetic passive aerosol sampler (PAS) design – evaluating PAS efficiency under various conditions and interferences, numerical simulation, and comparison with reference samplers.
  • Task 2. Development and validation of a standardized bench-scale particulate penetration test method.


  • Q1 Finalize analytical method of iron (II, III) oxide to meet required sensitivity.
  • Q2 Complete evaluating MPAS performance using the modified aerosol chamber/wind tunnel.
  • Q3 Finalize a deposition velocity model for the MPAS.
  • Q4 Submit a manuscript on evaluation of MPAS for internal peer review.


  • Manuscripts published or submitted to peer review journals (approx. 2)
  • Presentations at conferences (approx. 4)
  • This project has resulted in two employee invention reports


  • This project has contributed to the PPE section in Chapter 4 of the NIOSH Nanotechnology Research Center (NTRC) document titled “Progress toward Safe Nanotechnology in the Workplace” and the NTRC report titled “Approaches to Safe Nanotechnology: An Information Exchange with NIOSH” Feb. 2007.
  • This project has resulted in a new research proposal entitled “Nanoparticle penetration through protective clothing”, which has been selected and funded by NIOSH NTRC for a new FY09 project. Feb. 2007.
  • Improved standards and test methods for protective clothing used for protection against inert and biological aerosols.
