Brinkmann^® Reagents for Moisture Analysis

Since 1979, Riedel-de Haën has been innovating Karl Fischer reagent to eliminate or replace the traditionally unpleasant and hazardous components. HYDRANAL^® is the brand name of Karl Fischer reagents offered by Riedel-de Haën Laboratory Chemicals.

Features

• Broadest selection of volumetric and coulometric reagents and water standards—designed to meet application-specific requirements
• Contains no pyridine or carbon tetrachloride—safe and environmentally friendly. Most reagents are also free of 2-methoxyethanol and halogenated hydrocarbons. The new “E-type” reagents significantly reduce or eliminate the use of methanol.
• Supported by the Brinkmann Instruments Applications Laboratory—specialists are available to answer your questions and to help solve water analysis problems

One-component Reagents for Volumetric Titrations

• All reactants (iodine, sulfur dioxide, and imidazole) are in a single solution and use methanol as the solvent
• Unopened bottles have a minimum shelf life of two years
• Choose from Composite 5, Composite 2, or Composite 1 depending on your expected moisture content

Two-component Reagents for Volumetric Titrations

• Components are separated out into titrants and solvents, working in pairs—the separate solutions result in virtually unlimited shelf life

New “E-type” Volumetric Reagents

• Eliminate or significantly reduce the use of methanol and halogenated hydrocarbons
• Must be used in conjunction with liquid standards (works best with liquid samples)
• Suitable for use with some long-chained hydrocarbons and some ketones
• Two-component system—consists of Titrant 5E and Solvent E
• For one-component reagents—CompoSolver replaces methanol

• “AD” or “AG” type reagents—ideal for Metrohm coulometric cells without diaphragm separating the anolyte and catholyte
• Reduces halogenated hydrocarbon content—some contain long-chained alcohols to dissolve non-polar substances
• Reagents for two-component coulometric cells and aldehyde/ketone analysis are also available
• Reagents for Karl Fischer ovens are available—reduce the possibility of evaporation and burning

Certified Water Standards, Buffers, and Solvents

• Liquid standards in 0.10, 1.00, and 10.00 mg/g concentrations with a certificate of analysis
• Solid/powdered standards include sodium tartrate 2-hydrate and sodium citrate 1-hydrate
• Buffers and solvents available for aldehyde/ketone samples, samples requiring pH adjustment, and for improving sample dissolution
