- Scope
- This method specifies the analytical method for the determination of germanium by hydride generation atomic fluorescence spectrometry. This method is suitable for the determination of germanium in various foods and the determination of germanium-132 and inorganic germanium in health drinks. The detection limit of this method is 3.5 ng/mL; the linear range of the standard curve is 0ng/mL~100ng/mL. When determining the total germanium in the sample, the recovery rate of the method is 84.0%-93.2%. When determining germanium-132 and inorganic germanium in health drinks, the recovery rate of the method is 94.6%-103.4%.
