Karl Fischer Reagents for Moisture Analysis
Karl Fischer Titration (KF, or KFT) is the leading method for measuring water content in a wide variety of products and industries, such as Chemicals, Petroleum Products, Foods, Pharmaceuticalsm and many others. There are two primary types of KFT - Volumetric and Coulometric.
Volumetric KFT is typically recommended for moderate-to-high water content determination in the range of 0.1% to 100%. On the other hand, Coulometric KFT is utilized for determination of water at very low levels, typically well below 1%. Most modern volumetric and coulometric reagents are characterized by high titration rates and produce accurate, reliable results.
In addition, Standards and Reference Materials are required to ensure accurate, precise, and reproducible titration results. Both solid and liquid standards with varying certified water contents are used for monitoring and qualification of KF instrumentation.
VWR's portfolio includes a wide variety of KFT reagent and standard types, all produced under exacting quality control using validated procedures for highest possible accuracy and precision.
HYDRA-POINT coulometric reagents are designed to deliver faster analyses, lower detection limits and increased accuracy
No matter what your requirements are for volumetric systems, HYDRA-POINT™ Karl Fischer reagents make water determination easy and trouble-free
Since the 1980's, EMD Millipore has been marketing leading-edge, high performance reagents, quality water standards, and auxiliaries for Karl Fischer analysis under the Aquastar® brand name
Reagents and standards include a lot-specific Certificate of Analysis. NIST water standards include a certificate to indicate traceability to standards provided by the National Institute of Standards and Technology.
Our premium Hydranal™ product range for pyridine-free and ethanol-based water determination by Karl Fischer titration (KF titration) is comprised of one- and two-component reagents for volumetric Karl Fischer titrations
Coulometric Karl Fischer titrations normally require two reagent solutions: an anolyte (the solution in the anodic compartment) and a catholyte (the solution in the cathodic compartment).
