A Passive Sampler for Determination of Nitrogen Dioxide in Ambient Air  Dan Xiao, Lianzhi Lin, Hongyan Yuan, Martin M. F. Choi, and Winghong Chan
This article describes the use of a passive sampler for detecting and collecting nitrogen dioxide, NO2, in ambient air. This device is based on microporous PTFE membranes that allow air samples to diffuse through and subsequently react with an absorbing reagent solution. The absorbance value of this reagent is proportional to the NO2 concentration in ambient air. It has been successfully applied to determine the NO2 concentrations in various sampling sites.
