Set of AN-ZP01 and AN-ZP02

The set of soils consist of two natural agricultural soils differing in elemental composition.

AN-ZP01: Heavy loam with normal analyte levels.

AN-ZP02: Silty clay loam contaminated with some heavy metals

contents of element extractable fractions with aqua regia according to ISO 11466

Packing:

50 g of powder of the respective soil with a particle size of less than 100 µm in amber glass bottle.

Intended use:

This certified reference material is intended primarily for use in realizing metrological traceability, validation of analytical methods and the transfer of property values by total element contents to other materials of similar composition.

Recommended analytical methods for method dependent measurements:

Flame AAS, ETA-AAS, ICP-OES, ICP-MS, AMA-254
