Abstract
A process for simultaneously blowing a gas jet onto a sample 6 to be analyzed and subsequently focusing a laser beam 4 onto the sample so as to produce a plasma 12 on the surface of the sample. An analysis is made of the spectrum S' of the light radiation emitted by the plasma and this spectrum analysis provides the basis for determining the composition of the isotopic composition of the sample.
