Short summary
Soot particles with varying amounts of secondary organic matter coating were generated and used to compare a series of aerosol-absorption-measuring instruments: filter-based and photoacoustic instruments as well as photo-thermal interferometers. Significant deviations in the response of the instruments were observed depending on the amount of secondary organic coating. The system can be used for the inter-comparison and characterisation of instruments.
