Latest technique for purification, isolation and separation of organic compounds is :

Chromatography, a technique used by scientists to separate organic and inorganic substances, is the best and most recent method for isolating, purifying, and separating organic chemicals. Differential migration is the foundation of chromatography. A stationary phase is experienced by the solutes in a mobile phase. More time will be spent in the mobile phase by solutes with a higher affinity for it than by those who prefer the stationary phase. The solutes split when they pass through the stationary phase.
