Development of improved sampling and analysis methods for measuring organic, elemental, and water-soluble organic carbon in atmospheric aerosols and application to aerosol studies in Europe and tropical/equatorial and oceanic regions
… filter holder with two quartz fibre filters a denuder for volatile organic compounds and oxidising inorganic gases) and the tandem filter method (with two quartz fibre filters in series without denuder) were used in parallel for low-volume PM2.5 collections in several campaigns since 2002. It …

Droplet and Particle Dynamics in Aerosol Reactors and Environmental System
… air in both gas and particle phase. Diffusion denuders are used to separate gas and particulate SVOCs, and measure both phases separately to accurately access their transport in an indoor environment and their subsequent health risks. However, there are artifacts associated with this sampling …

Investigation of water vapor effects on the detection of nitric acid vapor with the tungstic acid technique
… coefficient and thus collection efficiency for denuder type measurement techniques may result with increased atmospheric water vapor (i.e., relative humidity). This study emphasizes the effect of water vapor (i.e., relative humidity) as a potential interferent for HNO₃ collection with the TAT …

Monitoring of atmospheric polycyclic aromatic hydrocarbons through optimization of analytical techniques
… polydimethylsiloxane (PDMS) traps as portable denuder devices for the monitoring of semi-volatile organic compounds (SVOCs), with most attention being given to the United States Environmental Protection Agency (US EPA) priority PAHs. These portable PDMS samplers are currently being analyzed by …

Characterization of carbonaceous aerosols from biofuel combustion: emissions and climate relevant properties
… by 13-40 percent when OC is removed by a thermal denuder upstream of the BC measurement. Biofuel combustion is a highly variable source. Emission fingerprint approach was developed and used to compare emissions from different combustion activities. Improved cookstoves reduce emissions by …
