Abstract
Abstract Charge exchange using the benzene molecular ion in a corona discharge atmospheric pressure ionization source is shown to be extremely sensitive for detecting low proton affinity compounds in air. Experiments performed on an Extrel API tandem mass spectrometric system indicated a limit of detection of 12.7 ppt for the detection of 2-chloroethyl ethyl sulfide in air.
