Abstract: An electric arc struck between a counterelectrode connected to the anode of a source of current, and a material to be sampled connected to the cathode, causes the ejection of very small droplets of the material. The droplets solidify and are carried away as an aerosol by the gas used to sustain the arc. The droplets are representative in their composition of the entire region of the material struck by the arc.
