fractionation
Noun: 1. The act or process of separating something into smaller parts or constituent elements. This often refers to a scientific or industrial separation process. 2. A specific chemical or physical process that uses differences in properties (like boiling point) to separate a mixture into its components. This is the core technical meaning.
Fractionation is primarily used as a technical term in chemistry, physics, and industry. It describes a systematic separation method. - The fractionation of crude oil in a refinery produces gasoline, diesel, and other products. - Air fractionation is used to produce pure oxygen and nitrogen. - The laboratory uses fractionation to isolate specific proteins from a cell mixture.
- Isotope fractionation: A process where the relative abundance of isotopes changes during a physical or chemical process. This is a key concept in geology and environmental science.
- Scientists study oxygen isotope fractionation in ice cores to understand past climates.
- Cell fractionation: A laboratory technique in biology to separate different parts of a cell (e.g., nucleus, mitochondria) by centrifugation.
- Cell fractionation allowed the researchers to study the organelles separately.
- Fractionate (verb): To subject to the process of fractionation.
- The chemist will fractionate the sample to obtain a pure compound.
- Fractional (adjective): Relating to or involving a fraction or the process of fractionation.
- They used fractional distillation to separate the liquids.
- Fraction (noun): One of the portions or components resulting from fractionation.
- The first fraction collected contained the lightest molecules.
- Separation
- Division

- Distillation (specifically for liquid mixtures using heat)
- Fractional distillation: A specific type of fractionation that separates liquids based on their different boiling points.
- Fractional distillation is a common fractionation process in chemistry labs.
- Fractionation column: The equipment used to perform fractional distillation.
