• Description:
  Today's scientists and engineers making aerosol measurements have available a diversity of aerosol monitors ranging from sample collection on a filter for later analysis to complex direct-reading instruments that detect the airborne particles in real time and display size distribution and chemical data. Instruments used for aerosol measurement frequently provide only an indirect measure of the desired information. For instance, commonly used optical particle counters measure an "optical size" that must then be converted to a physical or aerodynamic size using assumptions about particle properties. Most instruments also only operate over a limited particle size range, and often two or more instruments with different detection principles are used to cover a wider size range. Therefore, the aerosol practitioner must be able to assess the meaning and usefulness of data likely to be obtained with various instruments when selecting one or more for a specific purpose. Use of the simplest or most complex device may introduce errors in measurement and interpretation. While the data from the more complex sizing instruments may make errors evident and indicate the need for corrections, errors also occur in the less-sophisticated filter or inertial collectors. Lack of recognition of these errors may affect the interpretation of aerosol measurements. Approaching the aerosol measurement process with an appropriate plan will reduce the likelihood of major errors in the results. [Description provided by NIOSH]
