Journal ArticleDOI
New design of a high-performance denuder for the sampling of atmospheric pollutants
TL;DR: In this paper, an annular geometry-based diffusion denuder made of two concentric short tubes was developed and tested for laminar air flows as high as 20lmin−1.
Journal ArticleDOI
UV‐visible absorption cross sections of nitrous acid
TL;DR: In this paper, the authors presented measurements of the HONO UV-visible absorption cross sections with a spectral resolution better than 0.1 nm and a high signal-to-noise ratio.
Journal ArticleDOI
Annular denuder method for sampling reactive gases and aerosols in the atmosphere
Ivo Allegrini,F. De Santis,V. Di Palo,A. Febo,C. Perrino,Massimiliano Possanzini,Arnaldo Liberti +6 more
TL;DR: The annular denuder method (ADM) as discussed by the authors was developed to measure several gaseous and aerosol species without sampling artifacts, and it has been applied to the determination of gas phase and particulate matter.
Journal ArticleDOI
The nitric acid shootout: field comparison of measurement methods

TL;DR: The results from the three annular denuders do not agree; the ratios of means to the DDM value are 1.0, 0.8 and 0.6 as mentioned in this paper.
Journal ArticleDOI
Nitrous acid in the urban area of Rome
Karin Acker,A. Febo,Sebastian Trick,C. Perrino,Paolo Bruno,Peter Wiesen,Detlev Möller,Wolfgang Wieprecht,R. Auel,Marco Giusto,A. Geyer,Ulrich Platt,Ivo Allegrini +12 more
TL;DR: In the NITROCAT ground-based field experiment in May/June 2001, the highest HNO2 concentrations were found under high-pressure conditions with high nocturnal atmospheric stability and high values of pollutants as discussed by the authors.
