The components of a mixture are not chemically bonded to one another, so they can be separated from one another by physical processes such as filtration and/or evaporation filtration is a method for separating the solid components from the liquid components of a mixture. Quantitative and qualitative analysis of fluorescent substances and binary mixtures by use of shifted excitation raman difference spectroscopy. Various techniques for the separation of complex mixtures rely on the differential affinities of substances for a gas or liquid mobile medium and for a stationary adsorbing medium through which they pass such as paper, gelatin, or magnesium silicate gel. A separating funnel is used for the separation of components of a mixture between two immiscible liquid phases one phase is the aqueous phase and the other phase is an organic solvent this separation is based on the differences in the densities of the liquids.
