Separation and purification | Definition, Technology, Methods…
Some methods of separation (e.g., chromatography) work best with a small amount of sample, while others (e.g., distillation) are more suited to large-scale operations. Classification may also be based on the physical or chemical phenomena utilized to effect the separation. These phenomena can be divided into two broad categories: equilibrium ...
