AN-OK02

Sewage sludge with certified values of polychlorodibenzo-p-dioxins, polychlorodibenzo furans and toxic polychloro biphenyls.

It is siplified version of former CRM CZ 70006. The certified values for the most stable analytes were confirmed experimentally in three experienced laboratories.

The total I-TEQ value is approximately 150 ng/kg.

Packing:

60 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:

HRGC/HRMS
