Ion-molecule reactions of dimethyl ether cations with polycyclic aromatic hydrocarbons in a quadrupole ion trap mass spectrometer

The reaction chemistry between dimethyl ether (DME) cations and polycyclic aromatic hydrocarbons (PAHs) was elucidated by isolating three different types of DME ions using a quadrupole ion trap and reacting them individually with neutral PAH molecules eluting from a gas chromatographic column. The r...

Description
Summary:The reaction chemistry between dimethyl ether (DME) cations and polycyclic aromatic hydrocarbons (PAHs) was elucidated by isolating three different types of DME ions using a quadrupole ion trap and reacting them individually with neutral PAH molecules eluting from a gas chromatographic column. The results obtained show that the CH2OCH3+ ion (m/z 45) reacts via adduct formation followed by elimination of CH3OH, the (CH3)2OH+ (m/z 47) ion serves as proton donor and the (CH3)3O+ ion (m/z 61) does not yield any reaction products.
