Description

General description

The 0.1% water standard is prepared gravimetrically 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.

Packaging

10×8 mL in ampules
SKU-pack size numbers ending with a "3" are SmartChemicals with an RFID tag on the label for seamless data transfer to the instrument, e.g. xxxxxx1003 or xxxxxxx 4003. More information on www.sigmaaldrich.com/SmartChemicals

Application

It is used as a certified reference material (CRM) 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.” Although preferable for use in coulometric method, it can be used to verify the low water content by volumetric method.

Features and Benefits

  • Packed in convenient 8 mL glass ampoules with 10 single-use ampoules in a box
  • Supplied with a batch-specific certificate of analysis (CoA) having data on exact measured water content of the batch, uncertainty, method of analysis, the NIST batch, and minimum shelf life
  • Measured and qualified in an ISO/IEC 17025 and ISO 17034 accredited laboratory
  • Directly traceable to SI unit (kg) and verified by SRM 2890 from NIST
