Proton‐transfer‐reaction mass spectrometry (PTR‐MS) allows real‐time measurements of
volatile organic compounds (VOCs) in air with a high sensitivity and a fast time response …

Due to the great potentials in clinical diagnosis, disease state monitoring, and environmental
exposure assessment, the breath test is becoming one of the most desirable noninvasive …

During the NEAQS‐ITCT2k4 campaign in New England, anthropogenic VOCs and CO were
measured downwind from New York City and Boston. The emission ratios of VOCs relative …

Green‐leaf volatiles are commonly emitted from mechanically and herbivore‐damaged
plants. Derived from the lipoxygenase pathway, these compounds may serve as attractants …

Several volatile organic compounds (VOCs) have adverse health effects and contribute to
reactions promoting photochemical smog. The estimated world-wide average emissions of …

The present work shows the possibilities and limitations in modeling release kinetics of
volatile organic compounds (VOCs) from roasted and ground coffee by applying physical …

We present a new, off-line breath collection and analysis method, suitable for large
screening studies. The breath collection system is based on the guidelines of the American …

A proton transfer reaction mass spectrometer was used to measure the concentrations of
selected volatile organic compounds in the exhaust of a commercial turbofan aircraft engine …

Oxygenated volatile organic compounds (OVOCs) play an active role in tropospheric
chemistry but our knowledge concerning their release and ultimate fate is limited. However …

The contributions of molecular and fragment ions toward the disparate self-chemical
ionization (SCI) of α-pinene and camphene isomers were investigated. A kinetic model was …
