ELEMENTARY ANALYSIS DEVICE BY OPTICAL EMISSION SPECTROMETRY ON PLASMA PRODUCED BY A LASER

摘要

elementary analysis device by optical emission spectrometry onlaser produced plasma. this devicea pulsed laser source includes means (6), (8, 10, 12) in focusin the light of the source on the object to be analysed (2)in order to produce a plasma on the surface of the object, and means (16, 18).analysis of a spectrum of radiation of the plasma, means(20) for determining, on the basis of the analysis of the compositionthe basic subject, and of means (4) for travelthe object. the invention applies in particular to the control of materialsradioactive.
