Abstract
The reactions of monoterpenes and related C10 compounds with H3O+ in a proton transfer reaction-mass spectrometer (PTR-MS) were studied, with a view to better understanding the signal produced by this instrument when detecting these compounds. The monoterpenes α- and β-pinene, 3-carene and limonene produced fragment ions of masses 67, 81 and 95 as well as a protonated molecular ion of mass 137, while p-cymene (C10H14) produced ions of masses 41, 91, 93 and 119 in addition to mass 135. The fragmentation patterns were observed to vary as E/N was varied. Camphor (C10H16O) did not fragment within the E/N range 80–120 Td. The proton transfer reaction rate coefficients for these monoterpene species with H3O+ were found to be 2.2×10−9 to 2.5×10−9 cm3 s−1. For camphor the rate coefficient was 4.4×10−9 cm3 s−1. Water vapour pressure in the inlet air affected the fragmentation pattern for p-cymene, limonene and 3-carene. The uncertainties associated with the PTR-MS measurement of these compounds are discussed.

Abstract
Proton transfer reaction-mass spectrometry (PTR-MS) is a new and emerging technique for the measurement and monitoring of volatile organic compounds (VOCs) at low concentrations in gaseous samples in more-or-less real time. Utilising chemical ionisation, it combines the desirable attributes of high sensitivity and short integration times with good precision and accuracy. Recently it has been exploited in applications related to atmospheric science. Here, the principles of operation of the PTR-MS are described, its advantages and disadvantages discussed, its inherent uncertainties highlighted, some of its uses in atmospheric sciences reviewed, and some suggestions made on its future application to atmospheric chemistry.
