Azeotropic distillation. Any of several processes by which liquid mixtures containing azeotropes may be separated into their pure components with the aid of an additional substance (called the entrainer, the solvent, or the mass separating agent) to facilitate the distillation.ny of several processes by which liquid mixtures containing azeotropes may be separated into their pure components with the aid of an additional substance (called the entrainer, the solvent, or the mass separating agent) to facilitate the distillation.
Chromatography is a collection of laboratory techniques for separating a mixture of substances. These techniques involve passing the mixture from a mobile phase to a stationary phase. Each substance in the mixture does this at a specific rate, causing it to become separated as it moves into the stationary phase.The retardation factor (RF) is the relative amount of time that a particular substance spends in the mobile phase.ach substance in the mixture does this at a specific rate, causing it to become separated as it moves into the stationary phase.
