| Figures in brackets denote limits of quantification in mg/kg dry weight (elements) and % dry weight (oxides). Minimum sample amount: 5 g dry matter. Sample preparation may be required. Method: ICP-AES/ICP-QMS. |
|
|
Digestion: Samples are dried at 50°C after which As, Cd, Co, Cu, Hg, Ni, Pb, S and Zn are digested with nitric acid in sealed teflon containers in a microwave system and determined. Other elements are determined after fusion with lithium metaborate and dissolution of the fusion residue in dilute nitric acid. |
