A compact PTR-ToF-MS instrument for airborne measurements of volatile organic compounds at high spatiotemporal resolution

The analysis was extended to measurements of small oxygenated compounds by PTR- MS, with the goal of explaining ratios of these compounds to benzene in terms of production and loss

Emissions and ambient distributions of Biogenic Volatile Organic Compounds (BVOC) in a ponderosa pine ecosystem: interpretation of PTR-MS mass spectra, Atmos. C.: Adaption of a

These results demonstrate that two isobaric peaks at m/z 33 are well resolved and accurately positioned ( ∆ m ≤ 1.0 mDa) even with a relatively low mass resolving power of 900.

The spatial distribution of aerosol chemical com- position and the evolution of the Organic Aerosol (OA) fraction is investigated based upon airborne measurements of aerosol

Vertical and slant tropospheric NO 2 -columns from the new satellite instrument SCIA- MACHY on ENVISAT are validated by measurements of the Airborne Multi AXis DOAS

The emission of oxygenated compounds represented around 70 % of total organic aerosol for both types of vehicles measured by the

Earlier studies burning a vari- ety of biomass fuels found that OP-FTIR measurements of phenol accounted for the observed PTR-MS signal at this mass even at unit mass resolution,
