Reagent— Prepare the Karl Fischer Reagent as follows. Add 125 g of iodine to a solution containing 670 mL of methanol and 170 mL of pyridine, and cool. Place 100 mL of pyridine in a 250-mL graduated cylinder, and, keeping the pyridine cold in an ice bath, pass in dry sulfur dioxide until the volume reaches 200 mL.
• Volumetric titrations To ensure maximum accuracy of the results the amount of titrant used should (ideally) be between 20% and 90% of the burette volume. All volumetric Karl Fischer Titrators from KEM are equipped with 10 mL burettes. The samples should thus ideally contain between 4 and 18 mg of H2O if the titer of the reagent is 2 mg/mL .HYDRANAL™ - Solver (Crude) Oil Medium for volumetric one- and two-component Karl Fischer titration in oils (chloroform-methanol-xylene-based), CAS Number: mixture, .
