Abstract

See full text

The invention relates to a method of analyzing particles, in particular particles of diameter less than 1 μm, the method comprising the following steps:

    firing laser shots into a cold plasma (45) at low pressure;using an optical spectrometer device (60) to acquire emission spectra of the light emitted by the plasma as a result of the laser shots, in such a manner that for each acquired spectrum, an acquisition period begins no later than 100 ns after firing the laser shot; andanalyzing the particles present in the plasma on the basis of the emission spectra.
