My research in the topic of dry deposition velocity of atmospheric PAHs using PAS-PUF and Pas-DD sampler. For which, we were co-deployed the PAS-PUF and Pas-DD samplers in the different land use type. After collecting the samples, I have confusion on the validation of Pas-DD sampler. If anyone have idea about the validation of Pas-DD, it will be great help for me.

Thank you
