Abstract

A new quick-look method of sample analysis and a new equipment to carry out it, was developed by the authors. It's intended to use for special tasks occurring in the geology and in environmental protection. The layers in the ground are directly shot by a high energy pulse of a Nd:YAG laser and the picture of the excited plasma is observed trough a fibre optical system . The atomic emission spectra detected by the surface unit are stored in data files of special format. The spectrum files are analysed by the SAMPO 90 programme on an NB386 computer just at the site. The first methodological experiments were performed in the laser laboratories of Pees University. The new equipment consists of a sonde (measuring head) connected to the surface unit trough a fibre optical system. The surface unit contains the supply unit, the polycromator and a RAM. The measuring and the data acquisition is controlled by a 386 Note Book Computer. The whole system seems to be a portable laboratory to determine the components of rock samples or the contamination in the soil.
