General description

This Standard Reference Material (SRM) is intended primarily for use in calibration of instruments and techniques used for the determination of these vitamin D metabolites. A unit consists of twenty, two-milliliter ampoules, of four separate ethanolic solutions of vitamin D metabolites, five ampoules of each solution. Each two-milliliter ampoule contains approximately 1.2 mL of solution. The four separate ethanolic solutions of vitamin D metabolites are described below. For more information, please refer to theSDS andCOA.
