Abstract
The competition between charge transfer and proton transfer observed d uring the dimethylsulfide chemical ionization mass spectrometry is exp loited in order to discriminate PAH isomers undistinguishable in a gas chromatographic separation. Optimal conditions are reached if the rea ctant Proton Affinity (PA) is bracketed by the PAs of the isomer mixtu re consistuents.
