AN-OK01

Sewage sludge with certified values of selected PCB, PAH and elements.

The certified reference material was prepared by spiking selected relevant organic compounds into the orginal natural matrix.

Packing:

40 g of powder of the respective sewage sludge with a particle size of less than 100 µm in amber glass bottle. The sample is stabilized by radiation of 25kGy.

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:

Gas and liquid chromatography, flame AAS, ETA-AAS, ICP-OES, ICP-MS
