Double-accredited Water Standards for Karl Fischer Titration

Honeywell Research Chemicals has launched its first series of Hydranal double-accredited CRMs for Karl Fischer titration.

These new water standards are produced and certified in accordance with both ISO Guide 34 and ISO/IEC 17025, the so-called ‘gold standard accreditation’. The double accreditation means researchers can be sure of complying with the strictest regulatory requirements.

With increasing pressure from governing authorities and rising user demand for better quality measurement results, more and more laboratories are securing this level of accreditation. This enables them to demonstrate their measurement performance and the traceability of their results through CRM for both volumetric and coulometric testing.

The accurate calibration of analytical instruments and reagents is essential for precise, repeatable Karl Fischer titration. This validation process is performed with a specific amount of either pure water or a water standard; and while pure water can be satisfactorily used as a calibrator, accurate results are reliant on a range of factors such as the balance used, the volume of the burette, the Karl Fischer chemistry (titrant) and the know-how of the user.

Since the Hydranal product line was launched more than 35 years ago, Honeywell Research Chemicals’ laboratory in Seelze, Germany, has applied a high standard for production and quality control of Karl Fischer reagents and water standards. Customers’ results are directly affected by the quality of the certified reference materials they use, so the company has committed to continuously improving its processes to ensure that its products help them deliver the best quality research results. Attaining double-accredited CRM marks the latest step in that commitment.

All Hydranal water standards are tested against the NIST (National Institute of Standards and Technology, USA) standard reference material SRM2890, Water Saturated Octanol. Some of the standards are additionally tested against NMIJ (National Metrology Institute of Japan) CRM 4222-a.
