| Abstract: | A novel thermal dissociation atmospheric chemical ionization source(TDCI) was developed for rapid chemical ionization of ambient analytes in complex matrices.By coupling the TDCI source to a commercial LTQ XL mass spectrometer,the dissociation of chemical reagents such as ionic liquids was systematically investigated using multiple-stage mass spectrometric experiments.The primary ions generated through the thermal dissociation process of the ionic liquids were accelerated by the high voltage applied on the ... |
