Tandem Mass Spectrometer for the Detection of Nitroaromatic Compounds and Other Electronegative Species in Ambient Air

摘要

A tandem mass spectrometer has been constructed consisting of a quadrupole mass filter followed by a time-of-flight mass spectrometer. Ions are generated in an atmospheric pressure ionization (API) source, which allows for detection of certain types of compounds in ambient air. The combination of API with this tandem mass spectrometer offers the potential to do real-time monitoring of targeted compounds that are of environmental and other concern. 5 figs.
