The sample solution in 5.5 N-HBr medium was extracted by n-butyl acetate, using vanadium in 2N-HN03 medium as matrix modifier Ga, In and Tl could be measured less than O.OX ppm. The absolute sensitivity obtained for Ga, In and T1 were 5 .10-12, 9·10-12 and 9·10-12 respectively, The RSD of samples containing O.1µg/ml of Ga, 0.02 µg/ml of In and TI are 1.33% , 1.52 % and 1.4 7% respectively (n=11).
