German Merck/Merck Standard Water Sample, Article Number: 1.88051.0010, Coulometric Determination


Concentration: 1 g ≙ 1 mg H₂O 

Technique: Coulometric Determination
Density: 1.19 g/cm3 at 20 °C
Storage Temperature: 15 - 25°C

The concentration (efficiency) of Karl Fischer titrant decreases over time. Therefore, the titer, as a correction factor to offset this effect and the variations in equipment, personal operation, and laboratory conditions, must be determined immediately after opening a new bottle and should be verified regularly.

General description

The 0.1% water standard is prepared by gravimetry using high-purity water and reagents. It is characterized by a DIN EN ISO/IEC 17025 accredited quality control (QC) laboratory. The moisture content of the standard is determined by direct coulometric Karl-Fischer titration according to ISO 760.

Please browse the ISO certificate and on-site quality self-assessment to view the current certification of analysis.

Download the certificate at to view the certified values, including uncertainty and expiration date.

Applications

This product can be used as a certified reference material (CRM) to verify the accuracy of Karl-Fischer coulometric titrators in accordance with the requirements of ISO 9001 7.1.5 "Monitoring and measuring resources". It can also be used to check the accuracy of the measurement results according to the European Pharmacopoeia 2.5.32 "Determination of water (micro determination)". Although it is more suitable for coulometric methods, it can also be used to verify low water content determined by volumetric methods.

Features and advantages

  • Convenient 8 mL glass ampoule packaging, with 10 disposable ampoules per box

  • Provides a batch-specific certificate of analysis (CoA), with accurately determined batch water content data, analysis method, NIST batch, and minimum shelf life

  • Tested and verified by ISO/IEC 17025 and ISO 17034 certified laboratories

  • It can be directly traced back to the SI unit (kg) and verified by NIST SRM 2890

Packaging

If the last digit of the product packaging code (SKU-pack size number) is "3", such as xxxxxx1003 or xxxxxxx 4003, it represents a SmartChemical product. Data can be seamlessly transmitted to the instrument via the RFID tag on the product label. For details, please refer to /SmartChemicals.
