Determination of selenium in biological samples by gas-liquid chromatography with electron-capture detection
Journal of Chromatography
|June 1, 1977
Abstract:
Selenium can be determined quantitatively in biological samples after nitric acid-magnesium nitrate digestion and formation of 5-nitropiazselenole, by extraction into toluene for gas-liquid chromatography with electron-capture detection. The method is suitable for the determination of selenium in orchard leaves, bovine liver and human placenta, hair, blood and urine.
