Using fast response gas analyzers for combustion and RDE measurements

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 use of fast response gas analyzers for diesel engine and aftertreatment development

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.

The AAC – Classify particles from 25 nm to 5 μm+ without charging them

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).
