Summary The laser-ICP-AES, a typical two step procedure, was used for the direct simultaneous multielemental analysis of solids. Microamounts of all solids are ablated by laser-pulse radiation. The solid-gas aerosol formed is transported into the ICP, where the material is vaporized again, atomized and excited. The analytical performance of this technique is better than that of the laser microanalysis, which is characterized by an one-step procedure. Using the multishot technique in laser-ICP-AES the detection power of the laser AAS-ETA can be achieved (ppm level). The reproducibility of the technique is relatively good (RSD〈10%) in consequence of both the stability of the ICP and the application of inner standards. Calibrations are possible by application of compact solid standard materials (alloys), pressed powder materials and by using the method of multiple shots for compact rocks.
