Fractionation

Definition

Fractionation is the process of separating different components or isotopes from a mixture based on their physical or chemical properties. This technique is essential in the field of radiochemistry, especially when dealing with radioisotopes for therapeutic applications, as it allows for the isolation of specific isotopes needed for medical treatments while minimizing exposure to harmful ones.
