Inorganics
This material was blended from two soils, sourced from the Czech Republic and one
soil sourced from the UK.
This material is intended for use in validating methods for the determination of metals
in soil materials.
The extractable metal content refers to metals soluble in aqua regia using methods
based on ISO11466 (1995).
