The ORE Assay Standards (OREAS) range of CRMs have been developed specifically for the mining industry. ORE is proud to boast a high level of repeat business from many satisfied clients, ranging from major mining corporations to midtier and junior miners along with numerous commercial laboratories.
Note: If the absorbance of the test sample is outside of the absorbance range for the standards, then the assay must be repeated with a more appropriate dilution, if any. The linear range for the assay (and for most spectrophotometers is units. Table 1. Preparation of test samples for the Bradford protein assay.
