Environmental Teflon Chamber

Surfaces have shown to potentially play a large role in determining the chemistry of the indoor environment, and as such, have raised many questions regarding their possible impact on human health. However, studying indoor surfaces can pose some difficulties, due to their number and variability. Subjecting substrates to indoor emissions for offline analysis can provide information about the indoor environment that online measurements cannot capture. Using an environmental Teflon chamber with modular inputs and outputs was created to circumvent this issue. Preliminary studies using the Teflon chamber show that indoor surfaces from certain activities (cooking, cleaning, etc) can be recreated using model systems. In the future, we plan to use these complex model surfaces to bridge the gap between computational models and indoor field studies.
