Dr. Feilberg told us: "The PTR-MS instrument provide us with unique opportunities to investigate dynamic mass transfer processes at low concentrations for a relatively complex chemical composition. We have obtained very useful results related to e.g. emissions of odorous VOC from livestock production and biological air filtration of VOC."
