Flameless AAS provides a means to increase flame AAS sensitivity, by up to 200 times. Interferences from aqueous leachates and digestates are so great, however, that flameless AAS has found application mainly after organic extraction. Thereby, the analytical sensitivity is increased far beyond that of the SX/flame AAS methods. Interferences Interferences from other elements have been reported ...

An atomicabsorption method is described for the determination of vanadium in ores. With a nitrous oxideacetylene flame and 200 ppm of Al 3+ added to the sample, a sensitivity of ppm for 1% absorption can be obtained. Iron above interferes but can be extracted into isopropyl ether from 8M hydrochloric acid; the hydrochloric add itself then interferes and must be removed by evaporation.
