水溶液:第D类.规格 规格 Volumetric solution in accordance to the chapter reagents of the Pharmacopoeia (Ph Eur). Amount-of-substance concentration 0.1000 mol/l The concentration of this volumetric solution was determined with volumetric standard zinc (Merck article number 1.02409). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of +/-0.003 (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 682 (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard zinc, measured in the accredited calibration laboratory of Merck KGaA in accordance to DIN EN ISO/IEC 17025.
