Models of the dispersion of gases are useful for planning the response to an accidental or deliberate harmful gas release in a populous city environment. Heavier-than-air gases in particular will tend to not disperse safely away upwards into the a...

Common practice in the oil and gas industry is to burn unwanted or contaminated methane in a gas flare.  The burning efficiency of this flare is key to minimising the amount of methane which escapes in to the atmosphere; methane being a more signi...

With a focus on indoor air quality, we wondered what the particle emissions from a toaster would be. Before we even put any bread in, it turns out that the hot element is a significant source of very small particles which persist in the environmen...

With exceedances of permitted NOx levels in many urban environments and the introduction of clean air zones active or planned in a number of cities, the access of delivery vehicles and buses in to such areas has brought their emissions in to sharp...

We recently used our own in-house powertrain testing facilities to compare our fast emissions analysers (100 Hz) with conventional bench and FTIR analyzers.  See the video below for Euro 6 GDI cold start engine-out and tailpipe measurements of NO,...
