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, Gaithersburg, USA (NIST SRM 682 zinc) by means of volumetric standard zinc (Art. 1.02409). This volumetric standard is 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.
Merck have introduced into the range of Titripur® Titrants some packs with additional technology - Supelco® SmartTitrants that use an RFID tag to provide a seamless data transfer between the smart titrator and the RFID tag on the label of the bottle of titrant. It will ensure that all information needed for method execution, result calculation and documentation is transferred to the titrator equipped with this technology. MettlerToledo Compact and Excellence titrators include this technology. Please see ordering table below for packs with RFID tag.
Stability of product in Titripac packaging: Merck have carried out testing to show that products are stable for 36 months when in use and opened. Please see Technical report (Product specification) in the Related Information tab below.
