WATER STANDARD 0.01 % Chemical Properties,Uses,Production

Uses

It is used as a reference material to verify the accuracy of coulometric Karl Fischer titrators according to ISO 9001 chapter 7.1.5 “Monitoring and measuring resources”. It can also be used to check the accuracy of measured results according to European Pharmacopeia (Ph.Eur.) chapter 2.5.32 “Water Micro Determination”.

General Description

The 0.01% water standard is gravimetrically prepared from high-purity water and reagents. Its characterization is performed at an accredited quality control (QC) laboratory according to DIN EN ISO/IEC 17025. The water content of the standard is measured by direct coulometric Karl Fischer titration following ISO 760.
