   A fraction in chemistry is a quantity collected from a batch of a substance in a fractionating separation process.

A fraction can be defined as a group of chemicals that have similar boiling points.

3. Fractionation - Wikipedia

   en.wikipedia.org/wiki/Fractionation

   [1] [2] Fractions are collected based on differences in a specific property of the individual components. A common trait in fractionations is the need to find an optimum between the amount of fractions collected and the desired purity in each fraction. Fractionation makes it possible to isolate more than two components in a mixture in a single run.
