Fourier transform mass spectrometry (FT/MSR) has been recognized as a powerful analytical technique for the determination of elemental compositions and the molecular structure of materials. The simultaneous measurement of all species, produced in a single event, in a Fourier transform mass spectrometer provides a natural combination with pulsed lasers, where the pulsed laser is used to ablate and ionize a portion of a sample. This unique combination of lasers with FTMS provides elemental and molecular information from inorganic and organic materials and from surface layers and from bulk materials. Microanalysis of materials, allowing spatially-resolved high-resolution mass spectra to be obtained, is possible with small laser spot sizes and optical systems for viewing samples inside the mass spectrometer. The advantages of FTMS are reviewed, and several examples of laser probe FTMS are illustrated to demonstrate applications of the technique to industrial problem solving.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.
