Comparison of different instruments for particle concentration measurements.

Author(s) : WANG X. L., ZHANG Y. H., TAN Z. C.

Summary

Particulate sampling plays a very important role in indoor air quality and occupational exposure assessments. Most of the sampling instruments are designed and calibrated at standard conditions, but in real applications, they are used under different atmospheric conditions. The error can be so large that the results are misleading. In this paper, the sampling efficiency theory was reviewed, and laboratory and field experiments have been performed to determine the effect of sampling efficiency on particulate measurements for different types of particle instruments: a laser particle counter and an aerodynamic particle sizer.
