Discuss on traceability method of light-scattering airborne particle counter’s counting performance

The traceability of light-scattering airborne particle counter’s counting performance has received more attention, but has failed to settle internationally. This paper puts forward a traceability method of light-scattering airborne particle counter’s counting performance on single particle size, based on Anodic Aluminum Oxide (AAO) template andScanning Electron Microscope (SEM), by reforming the traditional standard airborne particle counter, building a measurement system including AAO and SEM, and utilizing the method of statistical physics in data processing to obtain more accurate measurement results. According to the actual test results and its uncertainty analysis, the traceability method of light-scattering airborne particle counter’s counting performance based on AAO and SEM makes sense in theory, and has certain research value on a solution to the traceability problem of light-scattering airborne particle counter internationally.
