particle separation

Particle separation involves processes that divide a mixture into its individual components. These components can range from molecules and atoms to larger particles like sand or bacteria. The goal is to transform a mixed sample into samples of single substances.1

Methods for particle separation are diverse and can be classified by the phenomena they utilize, such as equilibrium or rate processes. Common techniques include:1
* Filtration: Using a porous material to separate particles based on size.2
* Centrifugation: Employing centrifugal force to separate substances of different densities.34
* Elutriation: Using an upward fluid flow to separate particles by size and density.5
* Chromatography: Separating components based on their distribution between a mobile and stationary phase.6

These methods are crucial in various industries, from electronics requiring dust-free environments to biotechnology for cell separation.1
