Whether you are using your custom blend as a standard, tuning solution or quality control material stability and homogeneity are equally important. The certified NIST traceable documentation supporting the CRM not only includes detailed information relative to impurities recorded at the ppm level but also provides unequivocal information relative to the assigned values from data generated from at least two independent assay methods verified through student T-Test Validation. This provides total confidence that these ISO 17034 Certified Standards assure the highest confidence level in your work.
