Abstract: After optimizing the concentration. of HCl and NaI in the test solution, the concentration. of NaBH4, sample and reductant volume and flow rate, Ar carrier-gas flow rate and r.f. power, As (10 to 1000 ppb) was determined in NBS orchard leaves, coal fly ash and river sediment and NRCC MESS-1 and BCSS-1 standard reference materials with good accuracy and precision by using an ARL 34000 Quantometer. The coefficient of variation (n = 10) at the 100-ppb level of As was 7.2%, and the detection limit was 1.4 ng for a 0.17 mL sample volume The calibration graph was rectilinear for 0.01 to 1 ppm of As. Cobalt, Ni, Ag, Au, Bi, Te and Sn interfered. About 200 injections h-1 were possible.
