The matrix correction is suggested for determining Ga by flameless aas. The background is corrected by adding lmg/ml Ni using D2 lamp in 2 % nitric acid medium. The sensitivity of this method is 8.8 × 10-2g/1% Its C. V. for sample containing 0.02ppm of Ga is 1.81%(n=11).The re- coveries obtained by addition of standard Ga-solution are over 90 % . the mea- surable concentration range is O.OOOx-0.OOx % Ga.
