Quality Control Material (QCM)

Matrix:

Clay loam soil, normal analyte levels
Powdered material, grain size < 100 µm

Packing:

80 g in an amber HDPE bottle

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.
