Abstract
Sixteen international and six inter-laboratory geochemical reference
samples have been analysed for their selenium content. No previous
Se-data are available for thirteen of them. Selenium has been
separated from silicate matrix by volatilization and was determined
with flameless atomic absorption spectrometry. An outline of the
procedure is given. The limit of detection is 10 ng Se per 1 g
of sample. Time required for one full analysis is 1.2 to 2.5 hours
depending on amount of sample to be volatilized.
