The compound in the mixture that is the sublimate would be whatever compound has passed directly from the solid to the gas phase without entering the liquid phase in between.
It's not exactly a compound, but dry ice is often used due to it being quite readily available and very visible.
Several organic compounds can be purified by sublimation in vacuum.
These separation methods are not suitable for compounds; they are used for mixtures.
Sublimation apparatus is a piece of laboratory glassware used in the technique of sublimation usually used by chemists to purifycompounds. Typically a solid is placed in a vessel which is then heated under vacuum. Under this reduced pressure the solid volatilizes and condenses as a purified compound on a cooled surface, leaving the non-volatile residue impurities behind. This cooled surface often take the form of a cold finger. Once heating ceases and the vacuum is released, the sublimed compound can be collected from the cooled surface.
purification by sublimation is applicable when the solid has a relatively high vapor pressure at temperature below its melting point. it is also applicable when the purity has a lower vapor pressure than the purified, and when a small quantity of the solid is used. this process can also be used when compounds display characteristic property of condensing the solid state without passing through the liquid state.
The only requirement is that the solid must have a slight vapor pressure under the applied conditions. Sublimation happens below triple point pressure.
It is used to seperate substances of different melting point

Sublimation
Dye sublimation (correctly is dye diffusion) is used in printing.
The answer is Sublimation of an element or compound is the change from a solid directly to a gas with no intermediate liquid stage. Sublimation is a phase transition that occurs at temperatures and pressures below the triple point.

The phase of solid to gas is called sublimation.
Recrystallization and Sublimation are two commonly encountered methods of Purification. Several of these are done in the laboratory to obtain a pure sample of a particular organic compound. Recrystallization literally means to crystallize again. Sublimation involves heating the compound at low pressure from one apparatus and and condensing it in another. This is quite the same as distillation but of solid state.
The only requirement is that the solid must have a slight vapor pressure under the applied conditions. Sublimation happens below triple point pressure.
sublimation is a process in which a solid is directly converted to its vapour phase without facing liquid phase.
Chemists use a special sublimation apparatus.See this link for an image.
Sublimation Note: the term for the changing of a gas to a solid is condensation.
