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.
25-Hydroxyvitamin D3 Calibrant in Ethanol Level 1 [25(OH)D3 in Ethanol Level 1]
25-Hydroxyvitamin D3 Calibrant in Ethanol Level 2 [25(OH)D3 in Ethanol Level 2]
25-Hydroxyvitamin D2 Calibrant in Ethanol [25(OH)D2 in Ethanol]
