Laser Detection of Chemical Agents
Abstract
We have recently extended the gas-phase MPI technique to probe molecules absorbed on fused quartz surfaces. The phenomonology of the process is rich, showing wavelength-dependent fragmentation patterns. Our first generation surface/mass spectrometer system has a proven detectability limit of 4 less than 4 x10 to the 13th power molecules of dimethyl methyl phosphonate (DMMP) corresponding to an exposure to a DMMP partial pressure of .0000001 Torr for 1 second.
