Detection, Characterization and Classification of Biological Components in Aerosols by Time-Resolved Laser Pyrolysis Mass Spectrometry

摘要

The original objective of the work reported here was to develop computerized pyrolysis mass spectrometry techniques for detection of biological aerosol components in general and time-resolved Carbon dioxide laser pyrolysis MS methods in particular. Since laser pyrolysis methods require MS instruments with simultaneous ion detection capabilities, availability of a special miniature Mattauch Herzog MS system with electrooptical ion detector was an important element of the original proposal. Unfortunately, this system (funded by an independent DOD/University Instrumentation Program Grant) was never delivered due to bankruptcy of the manufacturer. Consequently, the work plan was focussed more strongly on the development of advanced chemical pattern recognition methods.
