| Abstract |
A rapid method of analysis for metal particles is described. Thallium particles (in the form of thallic oxide) were collected by passing contaminated air through a filter or by wiping a contaminated surface with a filter. The mass of thallium particles on the filters was determined in less than one minute using a laser-induced breakdown spectroscopy technique: a series of laser sparks was formed across the filter surface which vaporized the particles and excited the resulting atoms; thallium was detected by temporally and spectrally resolving the spark light. The method may be developed for the analysis of other types of metal particles. |
