詳細

詳細

This Standard Reference Material (SRM) is intended for use in preparing solutions for calibrating electrodes for pH measuring systems. SRM 191d consists of two components, each prepared to ensure high purity and uniformity:Sodium Bicarbonate, NaHCO3 (191d-I); and Sodium Carbonate, Na2CO3 (191d-II). However, neither SRM component is certified for purity of substance. A unit of SRM 191d consists of 25 g of sodium bicarbonate (191d-I) and 30 g of sodium carbonate (191d-II), each contained in its respective clear glass bottle. For more information, please refer to the COA and SDS.
