Abstract
After acid decomposition of the sample, selenium hydride was generated by means of sodium borohydride, and the gas was swept through a resistance-heated quartz cell mounted in an atomic absorption spectrometer to determine as little as 5 ng/g selenium in 0.25 g rock sample. One-way analyses of variance of data from nine USGS standard rocks indicated no significant differences in selenium content among bottles of any of these rocks.
