Karl Fischer reaction is pH dependent, with pH 5-7.5 being the ideal range. Strongly acidic samples slow the reaction, while strong alkaline samples cause no end point. Both types of samples must be neutralized prior to titration. Hydranal™-Buffer Acid and Hydranal-Buffer Base are ready-to-use liquid buffer media solving that problem. Hydranal is offering a wide range of additional Karl Fischer titration products, including buffers to neutralize acidic or basic samples to reach ideal pH-value or suppress side reactions.
Honeywell Research Chemicals’ history in the industry dates back more than 200 years to when chemist Johann Daniel Riedel started production of pharmaceuticals in Berlin. Today, Riedel-de Haën™, Fluka™, Hydranal™, Chromasolv™, TraceSELECT™ and many other world leading brands are now part of the Honeywell Research Chemicals portfolio, providing researchers with a choice of high-quality, consistent chemical and analytical reagents, designed to improve productivity. The Research Chemicals business is headquartered in Seelze, Germany. It manufactures high-purity solvents and reagents for laboratory research and testing applications.
