The adaptation of a quadrupole ion trap mass spectrometer (QITMS) to allow for studies of ion-ion reactions in the dilute gas-phase is presented. This system utilizes a dual-source design with electrospray ionization for the injection of multiply charged cations and an atmospheric sampling glow discharge interface (ASGDI) for the production of singly charged anions. The ASGDI source is mounted 90°...
Multiply-charged cations derived from the positive ion electrospray of the oligonucleotide 5 -d(CTTAGCGCTAAG)-3 were subjected to reactions with the (M - CF 3 ) - and (M - F ) - anions derived from perfluoro-1,3-dimethylcyclohexane in a quadrupole ion trap. Both single strand ions and double strand ions formed from the self-complementary oligonucleotide were...
