Abstract

Inertial impaction theory was used in the design and construction of a prototype PM 2.5 aerosol sampler. This prototype, consisting of just an impaction stage and a pump to move air through it, was subjected to collocation tests with MiniVol^TM samplers at different sampling sites, and filter analysis by means of stratified particle counting under an optical microscope. The average percent error for the collocation tests was 20.7% and the efficiency computed from stratified counting was 96.4%. While no definite conclusions regarding the prototype's performance may as yet be made, the trend in the collocation data and the high computed efficiency suggest that the construction of a low cost sampler may indeed be feasible.
