Metranal 1

Matrix reference material of river sediment.

Packing:

80 g in amber HDPE bottle. The sample is tabilized by radiation 25kGy.

Intended use:

The material is primarily designed for internal and external quality control purposes in the determination of total element contents and contents of element fraction extractable by the below described conventional procedures in soils and materials of similar matrix (quality control charts, interlaboratory comparisons, estimation of bias etc.) but not for ensuring traceability of measurements and calibration purposes.
