Paper Abstract

Direct analysis of solid materials without sample digestion are requirement in analytical plasma emission spectrometry. Laser ablation permits the production of fine particles to be atomized, excited and ionized in a secondary source such as an inductively coupled plasma. Laser characteristics such as the pulse duration, the beam shape and the wavelength seem to play a significant role in the shape of the crater and the amount of ablated material. A Nd:YAG laser at 1064, 532 and 355 nm has been compared with a XeCl laser at 308 nm. Using the various lasers, crater shapes are described and amounts of ablated material are compared.
