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).

Fast response NOx, HC and CO&CO2 analyzers with millisecond response times for measuring cycle-by-cycle emissions from combustion systems and very transient aftetreatment events. This includes some RDE data from light and heavy-duty vehicles.

An overview of how fast response gas analyzers are used for various applications such as cold start, catalyst heating strategy, fast EGR measurement and on-board NOx measurement for RDE applications.

The Cambustion DPG is a system for the complete automated testing of Diesel and Gasoline Particulate Filters. Based around a Diesel burner and accurate flow bench, the DPG facilitates testing of GPFs and Light, Medium and Heavy Duty DPFs at full scale flows and temperatures, with the capability to load soot, regenerate the filter and conduct flow tests. The DPG is used in both Quality Assurance testing and for R&D applications.
