Chromatography technique is best used to separate dyes.
Chromatography is employed to separate complicated mixtures like colored dyes from ink. In natural action, substances are separated as they travel in an exceedingly mobile section that passes through a stationary section. These area unit typically colored substances like food colourings, inks, dyes or plant pigments.
Chromatography is a surface impact therefore chemicals within the dye or liquid mixture opened up as a result of they move at completely different speeds over the stationary solid paper. Mixtures of quite one dye is separated into the individual dyes victimisation natural action.

The method of heat transfer that does not require a medium is radiation. Heat may be transmitted across void space through thermal radiation, commonly known as infrared radiation.
No mass is transferred and no medium is required during radiation. Radiation is the only method of heat transmission that does not need a substance, such as the heat released by the sun or the filament of a light bulb. There is no material medium necessary for the propagation of electromagnetic waves, often known as radiation. Only in a vacuum can we observe the perfect transfer of energy, because when radiation travels through material, part of its energy is lost. (Subject to the material property)
Conversely, in the instance of Conduction.
