Title Collection efficiency of a personal sampler for microbiological aerosols
Bibliographic information Dec. 1991, Vol.52, No.12, p.516-520. Illus. 8 ref.
Abstract A modified personal impinger (MPI) for sampling airborne microorganisms was tested for collection efficiency with the jet nozzle placed at various positions above and below the liquid surface. Results showed that the MPI functions according to impactor theory when operated with the flask bottom as the impaction surface, e.g. when the jet nozzle is positioned 4mm from the flask bottom. Also, impaction in the liquid or on the liquid surface will result in less efficient collection of small particles.
