The Karl Fischer Reagents consist of a solvent Alcohol (ROH), a known concentration of Iodine (I2), a Base (RN) and Sulfur dioxide (SO2). Principle of Reaction. The Bunsen reaction between iodine and sulfur dioxide in an aqueous system is the basis for the Karl Fischer Reagents reactions.

HPLC Reagents is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture.
