Abstract
We describe four sensing and characterization technologies recently developed at Los Alamos National Laboratory; a select set of mass spectral and optical techniques is emphasized. This work describes new, or newly developed, technologies which can be used for on-site, at-line and laboratory analyses. These include two each of optical-and mass spectrometric-based systems. We describe first a field deployable mass spectrometer, based on an ion trap analyzer, and variants of that system. We then describe a hand-held, battery-operated optical spectrometer, usable in either absorption, or fluorescence excitation mode. A laser-based mass spectrometer is also described, which used a minimal tunable laser system, and a time-of-flight mass spectrometer. Finally, a Zeeman effect optical diffractomer is described.
