ROBOTIZED SAMPLING DEVICE FOR GRAPHITE-FURNACE ATOMIC-ABSORPTION SPECTROMETRY SLURRY ANALYSIS WITH VARIAN SPECTRAA INSTRUMENTS

There is a growing interest in the determination by electrothermal atomic absorption spectrometry (ETAAS) of elements in solid samples without a dissolution stage, to avoid contamination and losses during the preparation of the sample. This approach may be particularly convenient when only small amounts of sample are available. Details of the above-mentioned program for the adaptation of the Gilson sample changer to Varian SpectrAA systems (X,Y,Z positions, timings etc.) are available on request. © 1993.
