Variety of methods and instruments are available to today's scientists and engineers making aerosol measurement, that range from filter-based sample collection for off-line laboratory analysis to sophisticated near-real-time instruments that detect the airborne particles and display size distribution and chemical data in real time. Instruments used for aerosol measurement frequently provide only an indirect measure of the desired particle property. For instance, commonly used optical particle counters measure an "optical size" that must then be converted to a physical or aerodynamic size - if needed - using assumptions about particle properties. Most instruments also only operate over a limited particle size range, and often two or more instruments, each using a different measurement principle, must be used to cover a wide size range. Therefore, the user must be able to assess the meaning and usefulness of data likely to be obtained with various instruments when selecting one for a specific application. Lack of recognition of measurement errors may affect the interpretation of aerosol measurements. Approaching the aerosol measurement process with an appropriate plan will reduce the likelihood of measurement errors.
