| The concentration is determined by volumetric titration and refers to 20°C.The certified value is traceable to a primary standard from the National Institute of Standards and Technology USA (NIST SRM 723Trishydroxymethylaminomethane) by means of volumetric standard Trishydroxymethylaminomethane (Art. 1.02408), certified by the accredited calibration laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO 17025.The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%.All measurements are carried out in the laboratory of Merck KGaA, Darmstadt, Germany.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. |
