Overview: 
The Aerodynamic Aerosol Classifier (AAC) selects particles over a very wide size range by aerodynamic diameter for further online analysis, including, but not limited to counting (CPCs), chemical speciation (mass spectrometers or GC), in vitro and in vivo studies & instrument calibration. The AAC can also now produce a size spectrum by scanning when connected to a CPC. Unlike the DMA (differential mobility analyser), used for similar purposes in the past, the AAC does not involve particle charging in its measurement technique, so is not subject to multiple charging artefacts. It also suitable for classifying much larger particles than is possible with a DMA. In this webinar Dr Jon Symonds covers the principle of the AAC, before describing a number of applications, in the fields of atmospheric science, morphology determination, filtration and size-based calibration of other instruments (such as optical particle counters and CPCs).
