Kaliumiodat opløsning 1/60 mol, Titripur®, Supelco®Leverandør: Merck
The concentration is determined by volumetric titration and refers to 20°C.
The certified value of this volumetric solution was determined with sodium thiosulfate standard solution (article number 1.09147).
The sodium thiosulfate standard solution is standardized and traceable to a primary standard from the National Institute of Standards and Technology USA (NIST SRM 136 potassium dichromate) by means of volumetric standard potassium iodate (article number 1.02404).
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 calibration laboratory D-K-15185-01-00 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.
