詳細

詳細

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.

アプリケーション

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”.

特徴および利点

• Packed in convenient 8 mL glass ampules. Each box contains 10 single-use ampules
• 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 accredited laboratory
• Directly traceable to SI unit (kg) and verified by secondary reference standards 2890 from NIST
• Shelf life of 18 months

包装

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.
