Laser Microprobe Mass Spectrometry LASER MICROPROBE MASS SPECTROMETRY: POSSIBILITIES AND LIMITATIONS
Laser microprobe mass spectrometry (LMMS) employs an intense UV pulse from a focused highpower laser to evaporate and ionize a microvolume (% 1 um3) of solid samples at relatively elevated energy density (106-101’ W cmm2). The ions produced by the interaction of photons with the condensed phase are then mass analyzed in a time-of-flight mass spectrometer and yield a complete mass spectrum on ea...
متن کاملLaser Microprobe Mass Spectrometry: Possibilities and Limitations
Laser microprobe mass spectrometry (LMMS) offers a great potential for inorganic analysis and speciation as well as for organic structural characterization. This remarkable flexibility makes the results critically dependent on the experimental conditions, however, so an exact description is hard to achieve, since inaccessible local parameters are involved. The paper deals in detail with this as...
متن کاملLaser microprobe mass spectrometry of quaternary phosphonium salts: Direct versus matrix-assisted laser desorption.
The use of laser microprobe mass spectrometry (LMMS) for the structural characterization of thermolabile quaternary phosphonium salts has been evaluated. A comparison has been made between LM mass spectra obtained by direct analysis of "neat" organic salts and the corresponding "matrix-assisted" LM mass spectra. Main limitations of LMMS for the direct analysis of neat organic salts (i.e., no ma...
متن کاملMicroscopical speciation analysis with laser microprobe mass
This paper presents a set of data which compares the potential and limitations of laser microprobe mass spectrometry (TOFLMMS and FT-LMMS) and static secondary ion mass spectrometry (S-SIMS) for inorganic speciation at a microscopical level. In general LMMS yields prominent signals of adduct ions consisting of the intact molecule combined with a stable ion, which allows a direct identification ...
متن کاملAnalytical mass spectrometry of herbicides.
Herbicides are chemical substances that are applied to agricultural soils, gardens, lawns, or plants to destroy or to prevent the growth of undesirable vegetation. The herbicides included in this review are generally synthetic organic compounds that are ingredients in commercial herbicide products that were designated active during late 2002 in the U.S. Environmental Protection Agency's databas...
