The purpose of this project was to design, construct, calibrate, and field test a mobile ambient particulate matter sampler (Wide Range Aerosol Classifier) to collect size-classified samples of large aerosol particles. The sampler design was based on a similar stationary sampling system previously constructed by the Principal Investigator, Dr. Dale Lundgren. The sampler is fitted into a trailer and consists of a large, high flowrate inlet from which 5 isokinetic samples are withdrawn. Four of the samples are passed through single stage impactors with different cutpoints while the fifth is passed through a total particulate matter filter. The 4 impactors were designed to collect particles greater than 7.5 mm, 15 mm, 30 mm and 60 mm diameter. Aerosol particles smaller than 7.5 micrometers are sized by using separate lower flow rate cascade impactors following the last single stage impactor. An accompanying analysis lab was set up in a mobile van. Analysis equipment includes an analytical balance and a sample equilibration chamber. The mobile sampler was briefly field tested in Gainesville, Florida.
