Aquastar® Two Component Karl Fischer Titrants by Merck – Enhanced Accuracy and Speed for Reliable Water Determination

Accurate water determination is vital in analytical chemistry, especially when dealing with challenging matrices or high acidity or alkalinity. Aquastar® two component Karl Fischer titrants by Merck deliver superior speed, robust buffer capacity, and stable titers—helping labs achieve consistent, high-quality results while meeting industry demands for reliability and efficiency. This page explores key benefits, compositions, and ordering details for Aquastar® titrants.

Benefits of Aquastar® Two Component Karl Fischer Titrants

• Slightly faster titration: Provides slightly faster titration than one component reagents, helping improve analytical workflow efficiency.
• High accuracy for reliable results: Supports accurate water determination with reliable analytical results.
• Better buffer capacity: Offers improved buffer capacity for demanding titration conditions.
• Higher titer stability: Delivers higher titer stability and greater long term stability than one component titrants.
• Consistent high quality results: Being without chloroform helps ensure consistent high quality for comparable results.
• Suitable for repeated matrix analysis: Is often used for series from the same sample matrices.
• Suitable for challenging sample chemistries: Is often used for strong acidic or alkaline samples.

Features of Aquastar® Two Component Karl Fischer Titrants

• Two component system design: Aquastar two component Karl Fischer titrants are formulated so that the titrant contains iodine and methanol or alcohol, while the other Karl Fischer reaction components are provided separately in the solvent.
• Titrant composition: The titrant contains iodine and methanol.
• Solvent composition: The solvent contains sulfur dioxide and a suitable base dissolved in methanol.
• Working medium: The Aquastar® solvent is used as the working medium in the Karl Fischer cell.
• Paired reagent use: Aquastar® two component titrants must be used together with Aquastar® two-component solvent.
• Concentration options: Two different titrant concentrations are available to support higher and lower water content.
• Formulation characteristic: The two component reagents are provided without chloroform.
