Product Overview

New formulation. Not regulated for transport. For volumetric analysis. Suitable for general purpose applications as well as for aldehydes and ketones. GFS Chemicals – 1 L, Watermark Karl Fischer Reagent, 5 mg/ml solution, SKU 17301. Volumetric titration is typically selected for samples in the 100 ppm to 100% water content range, although sample analysis down 10 ppm water is possible. One component KF reagents are the most popular as they are the least expensive and don’t always require a special solvent. In one-component Karl Fischer Titration, a titrant with a known concentration is reacted with a sample in a vessel solvent, ultimately consuming the water in the sample. The titrant contains all the components required for the KF reaction: iodine, base, sulfur dioxide and a solvent medium. The vessel solvent is chosen to match the sample dissolution characteristics. By measuring the volume of the titrant added, the amount of water in the sample can be calculated. The Watermark® product line includes reagents with titer values of 5 mg/mL, 2 mg/mL and 1 mg/mL, covering an array of applications.

GFS Chemicals is the leading supplier of Watermark Karl Fischer.
