摘要：
Speciation and metabolization of platinum and selenium in biological systems was investigated by HPLC coupled to low and high resolution ICP-MS. Using size exclusion chromatography more than 90% of the Pt found in a grass sample was present in an inorganic fraction while the remaining 10% occurred in 4 different organic fractions. Selenium Was studied in sea-gull eggs by use of reversed-phase HPLC. Six separated Se-organic compounds were observed, the major compounds being selenocystine and selenocystamine.
