Laser microprobe analysis (LMA) offers good spatial and depth resolution for solid sampling of virtually any material. Coupled with numerous optical spectroscopic and mass spectrometric detection methods, LMA is a powerful analytical tool. Yet, funda

Two acoustooptical deflectors placed orthogonal to each other allow the scanning of a laser beam in two dimensions without mechanical movement. A complete scan is possible in 50 micros, providing a spatial resolution of 20 x 125 spots. This is used t

To understand the laser desorption process for large molecules, one needs information about the neutral species that are formed. For absorbing dye molecules, this can be accomplished by imaging the plume over its lifetime of a few milliseconds with a

Theory and experiment show that the precision of quantitative derivative ultraviolet spectrometry depends on the choice of derivative order, degree of smoothing, convolution method of smoothing or derivatization, and power of the reference beam. Exce

A hot cell-based solid sampling system has been developed for application to the analyses of irradiated materials such as metallic reactor fuel from a nuclear reactor, and radioactive waste forms. This system employs one of two sampling techniques, g

Lasers have been used since 1962 to vaporize small amounts of solid inorganic material. More recently their use to vaporize (desorb) large thermally labile organic molecules has grown. The larger and more polar the molecule, the more difficult it is

Two new techniques for characterizing particles generated in transient vaporization events are described. Acousto-optical deflection allows temporal and spatial information to be obtained with good resolution. In a transmission mode of observation, r

We report the application of a light scattering technique for the determination of particle sizes in a laser-generated plume. This procedure is based on the dissymmetry ratio obtained for observation at different angles relative to the excitation sou
