Description
|
The material is intended for the verification of analytical results obtained by standardised procedures as well as for the validation of modified or new analytical methods.
The material is provided as a powder with particle sizes below 63 µm in a 100 mL screw-capped brown glass bottle containing (52 ± 1) g. The starting material was a mixture of sediments collected at different locations in the eastern part of Germany (river Elbe near Magdeburg, river Weiße Elster near Leipzig, Finow Canal near Eberswalde). The raw material was freeze-dried and afterwards the fraction passing a 2 mm screen was ground in a ball mill (with grinding bowls and balls made of zirconia) completely to particle sizes below 63 µm. Homogenisation and bottling of the ground material was performed using a spinning riffler. keywords : Environmental material, Particulate matter, Soil/Sediment, Trace elements, Heavy metals, Fractionation analysis, Aqua regia soluble fraction |
