Aquastar® CombiTitrant 5 Keto by Merck: Methanol-free Karl Fischer Reagents for Precise Water Determination in Aldehydes and Ketones

Accurately determining water content in aldehyde and ketone samples can be challenging due to side reactions using standard Karl Fischer reagents. Aquastar® CombiTitrant 5 Keto by Merck, paired with CombiSolvent Keto, eliminates methanol-induced errors, ensuring reliable and fast titrations. Discover how these specialized reagents address industry requirements for precise analytical results and optimize your water analysis workflow.

Why Choose Aquastar® CombiTitrant 5 Keto

• Reduced side reaction risk: Supports more reliable Karl Fischer water determination in aldehyde and ketone samples by helping prevent side reactions and unreliable endpoints associated with standard methanol-based reagents.
• Fast titration performance: Enables fast titration to suppress bisulfite addition during water content determination.
• Methanol-free operation: Avoids methanol-related side reactions that can interfere with water analysis in these sample types.
• Improved result quality: Delivers improved accuracy and reproducibility for water determination in samples containing aldehydes or ketones.
• Chloroform-free formulation: Offers a reagent option without chloroform.
