Calibration of the Anderson 2000 disposable air sampler.

The Anderson Disposable Sampler is an efficient instrument for collecting airborne particles in the size range 0.8 to 10.5 microns. When used for microbiological aerosols, we would expect almost 100% of the particles in this size range to be collected. These particle sizes are of special significance for anyone interested in respiratory and other infections in hospitalized patients. The 50% effective cut-off diameter of stage 1 of this sampler is 8.0 microns for spherical particles. This instrument is simple to operate, uses standard size Petri dishes, has a high collection efficiency, and does not require a flow regulator. It should find wide use in hospitals, clean room technology, and industrial applications where microbial air quality is significant.
