Report no. 1/21: Organic aerosols (OA) are an important component of ambient particulate matter (PM) but their origin and formation is not well understood. Traditionally, OA have been described by two classes: a) primary organic aerosol (POA) and b) secondary organic...
Results of a comparative pilot field test study of a first generation Quantitative Optical Gas Imaging (QOGI) system
Report no. 23/20: Quantitative optical gas imaging (QOGI) is a new system to detect fugitive emission sources and quantify their mass release rates. This report presents an evaluation of QOGI technology compared to other techniques (Sniffing/EPA Method 21 and high...
Three-way catalyst performance using natural gas with two different sulphur levels
Report no. 6/20: Stoichiometric engines running on natural gas rely on three-way catalysts to meet limits e.g. Euro 6 regarding emissions of hydrocarbons (including methane), carbon monoxide and oxides of nitrogen. As is well known from decades of industry experience...
