| Abstract |
A low pressure impactor aerosol sampler was designed fabricated and tested. The system injects a fixed aerosol flow rate of 1 cfm at inlet conditions and causes the particulate matter to be separated and collected on four atmospheric pressure and three reduced pressure imapction stages and an after-filter. Cutpoint sizes of the stages are 9.7, 5.0, 2.46, 1.21, 0.335, 0.141, and 0.05 micrometers for spherical particles with a density of 2 gm/cc3. Each of the impaction stages is fitted with a glass fiber media collection substrate to facilitate gravimetric analysis of the collected samples. |
