Aquastar™ Titrant 2 Volumetric Solvent, 1 L

Unlike one-component volumetric Karl Fischer analysis, in two component volumetric reagent systems, the titrant contains only iodine and methanol, while the solvent containing the other KF components - sulfur dioxide and a suitable base dissolved in methanol - is used as the working medium in the titration cell. Two-component reagents are distinguished by greater long-term stability and faster titration times than one-component reagents. The former is due to the fact that the KF reaction components are divided between the two reagents, making each of the reagents less susceptible to slow side reactions over time. Faster titration times result from the initial availability of sulfur dioxide and base in the solvent to which the sample to be analyzed is added. Additionally, two-component reagents typically produce slightly more accurate results than one component reagents due to the higher buffer capacity of the solvent.
