Comparisons are made with determinations by atomic absorption and X-ray fluorescence spectrometric procedures to indicate agreement or bias of the analytical results, and the presence of systematic errors.", pages = "335-343", url = "http://www.ingentaconnect.com/content/sas/sas/1976/00000030/00000003/art00014", doi = "doi:10.1366/000370276774457173", keyword = "Arc, dc, Atomic absorption spectrometry, Emission spectroscopy, X-ray fluorescence" }
