| The amount-of-substance concentration of this volumetric solution is analyzed by our quality control laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025.The concentration is determined by volumetric titration and refers to 20°C.The amount-of-substance concentration of this volumetric solution is determined with standardized thiocyanate solution (article number 1.09079). The thiocyanate solution is standardized by silver nitrate solution (article number 1.09081) which has been standardized against volumetric standard sodium chloride (article number 1.02406).This volumetric solution is traceable to a primary standard reference material (SRM) from the National Institute of Standards and Technology, Gaithersburg, USA (NIST SRM 999 potassium chloride) by means of volumetric standard sodium chloride (article number 1.02406), certified reference material according to ISO 17034, analyzed by our accredited calibration laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025. The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%.Note: The titer is a correction factor to correct for variations of the volumetric solution, the titration equipment, the temperature and other laboratory conditions. For correct titration results it is recommended to determine a titer with the laboratory specific equipment and under laboratory specific conditions directly after opening a new bottle and at regular time intervals. |
