摘要：
A microscopic laser desorption/postionization Fourier transform mass spectrometer (LD/FTMS) is described. The lateral resolution can be <1 mu m with the inherent FTMS high mass resolution intact. Laser postionization allows a certain selectivity and an increase in sensitivity. This capability should allow materials characterization in a wide variety of cases. We demonstrate microscopic desorption and postionization for atoms and molecules.
