A proton transfer reaction mass spectrometry based system for determining plant uptake of volatile organic compounds

Abstract In order to evaluate the contribution that higher plants make to the removal of volatile organic compounds from the atmosphere, a measurement system consisting of a proton transfer reaction mass spectrometer (PTR-MS), CO 2 analyzer, diffusion devise and leaf enclosure was established. The uptake of VOCs by Golden Pothos ( Epipremnum aureum ) was investigated. The overall relative error associated with measurements made using this system was
