Styrene radical cations for chemical ionization mass spectrometry analyses of monoterpene hydrocarbons
Original language description
RationalenMonoterpene hydrocarbons play an important role in the formation of secondary aerosol particles and in atmospheric chemistry. Thus, there is a demand to measure their individual concentrations in situ in real time. Currently, only the total concentration of monoterpenes C10H16 can be determined by chemical ionization mass spectrometry techniques using reagent ions H3O+, NO+ and (C6H6)n+• without gas chromatographic separation.nMethodsnThe styrene cation C8H8+• was investigated as a reagent for chemical ionization of monoterpenes. The modified selected ion flow drift tube, SIFDT, technique was used to characterize the differences in product ion distributions between α‐phellandrene, α‐pinene, γ‐terpinene, β‐pinene, ocimene, sabinene, 3‐carene, (R)‐limonene, camphene and myrcene.nResultsnThe monoterpene molecular cation C10H16+• is the main product (about 90%) for all isomers except (R)‐limonene and camphene with an efficient channel of C8H8+•C10H16 adduct formation and γ‐terpinene with unexpectedly significant product ions at m/z 134 and 135 corresponding to losses of H2 and H.nConclusionsnUtilization of the styrene cation for the ionization of monoterpenes is beneficial due to the very low fragmentation of the product ions. Specific association product ions for camphene and (R)‐limonene and fragment product ions for γ‐terpinene allow them to be distinguished from other isomers that produce mostly the molecular cation.n
