A device for preparing a gaseous sample obtained from a solid sample. The device includes a laser source arranged to emit a laser beam which is capable of generating calcination and/or combustion of a portion of the solid sample, a collector arranged to collect a gaseous sample of a gas emitted during the calcination and/or combustion of the portion of the solid sample; the laser beam has an irradiance less than 5 MW/cmin a given impact zone on a surface of the sample, and including an optical fibre for propagating the laser beam between the laser source and the given impact zone on the surface of the sample.
