    Sublimation is a technique used by chemists to purify compounds. A solid is typically placed in a sublimation apparatus and heated under vacuum. Under this reduced pressure the solid volatilizes and condenses as a purified compound on a cooled surface (cold finger) leaving a non volatile residue of impurities behind. Once heating ceases and the vacuum is removed the purified compound may be collected from the cooling surface. For even higher purification efficiencies a temperature gradientis ap
