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.
Milestones
- 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.
