Abstract
There were few reports on the collection efficiency of the airborne bacteria sampler using biological particles in a laboratory.
We studied collection efficiency on the 5 kinds of samplers for biological particles using the test chamber atomized microorganisms and proved the slit sampler (casella) of the impaction type show surpassing collection efficiency in 1970. However, as the study was qualitative, we have developed the skillful method and designed the test equipment for collection efficiency using biological particles of the samplers and performed a quantitative experiment. (1993) As the results of these experiments, the collection efficiency of samplers indicates the significant difference and the collection efficiency of the portable type samplers indicates lower than that of the fixed type samplers.
Nakata et al. developed the portable sampler which has as high collection performance as fixed type samplers examined by the above quantitative method. (1999)
Here, we introduce these results.
