摘要：

A new experimental method was developed which combines an ion trap ion source with tandem mass spectrometry (MS/MS) measurements on a sector instrument. Ion trapping is achieved through a negative electron-space-charge potential well. Preliminary results on time-resolved collisionally activated dissociation spectra (CAD) for C7H7+ from toluene and benzylbromide are presented. The results indicate an increased tropylium to benzilium abundance ratio for toluene with increasing ion trapping time, in the range 2.2-50 mus.
