ABLATION LASER COUPLAGE TO PLASMA TORCH A TOMIC-EMISSION SPECTROMETRYIN A GLOVE-BOX

The direct analysis of elements in solids by plasma torch atomic emiss ion spectrometry is all the more necessary when it concerns radioactiv e and toxic samples as the setting into solution is quite long and gen erates radioactive waste. It can be achieved through laser ablation. T he study is composed of two parts: i) the achievement of a laser ablat ion system coupled with a plasma torch in glove-box. The choice of the suitable laser was set on an XeCl excimer laser. An ablation cell, ha ndy for use in a glove-box and developing a high transport yielding wa s created; ii) the evaluation of the analytic performances of the meth od on the beryllium, plutonium and uranium matrices.
