Box 60220 Reno, NV89506, USA Introduction Utilisation of spot tests and formvar replication together can give important information on the volatile components of atmospheric particles. In this study, we tested the response of different film preparation conditions to nitric acid, nitrate and sulfate containing droplets, NaNOg and NaSO4 particles. Experiments Droplets were generated via a nebuliser. Different concentrations of nitric acid, NaNOs and NaSC>4 solutions were used. Nitric acid containing droplets impacted on nitron doped wet formvar film.
