Accredited analyses are marked in bold. Figures in brackets denote limits of quantification in mg/kg dry weight. Minimum sample amount: 5 g dry matter. Price includes digestion. Delivery time: 10-15 days.

MG-2 may be supplemented with the additional elements.
| For the determination of B, an additional fee for the dissolution is charged. |
Digestion: For the determination of As, Cd, Co, Cu, Hg, Ni, Pb, S and Zn, the sample is dried at 50°C and dissolved in nitric acid/hydrochloric acid/hydrofluoric acid in a closed teflon vessel in a microwave oven (concentrations corrected to dry weight 105°C). Other elements are determined after fusion with lithium metaborate followed by dissolution in dilute nitric acid.
Additional costs for sample preparation may occur.
| Digestion using 7M nitric acid can alternatively be performed in autoclave. Please contact the laboratory for more information. |
