Description
Product description
GFS Watermark 5 mg/mL Single Solution, Non-Haz Karl Fischer Reagent is a one-component volumetric Karl Fischer reagent for routine moisture determination in compatible laboratory samples. The 5 mg/mL concentration is commonly used for volumetric KF analysis where a standard-strength reagent provides efficient titration performance.
This non-haz formulation is designed to simplify handling and transportation compared with traditional Karl Fischer reagents. GFS describes this product as a new formulation that is not regulated for transport and intended for volumetric analysis.
Unlike conventional methanol-based Karl Fischer systems, this specific GFS non-haz single-solution formulation is listed by GFS for general-purpose applications as well as aldehydes and ketones. However, aldehyde- and ketone-containing samples are reactive matrices, so reagent compatibility should always be confirmed against the current GFS documentation and the sample method before use.
Feature bullets

Technical note / application caution
Important: Standard Karl Fischer reagents are not automatically suitable for aldehyde- or ketone-containing samples. GFS lists this specific 5 mg/mL Single Solution, Non-Haz formulation for general-purpose applications as well as aldehydes and ketones, but compatibility should be confirmed with the current GFS Chemicals documentation before analysis.
