Description

The certified values delivered by this Standard Reference Material (SRM) are intended for validating methods for determining elements, vitamins, and cholesterol in whole milk powder and similar materials and for quality assurance when assigning values to in-house control materials. NIST-1549a consists of five heat sealed aluminized packets, each containing approximately 10 g of material. /// Sample value(s) - please ask for current certificate.
