solvent: 5 parts cyclohexane, 3 parts propanone, and 2 parts ethoxyethane. In chlorophyll chromatography, photosynthetic pigments such as chlorophyll, carotene, and xanthophyll can be separated using paper chromatography based on their solubility in the solvent and size. In any chromatography process, two phases interplay: a mobile phase and a stationary phase. In this technique, a concentrated spot of the pigment mixture is deposited at one end of a paper strip. WebFour primary pigments of green plants can easily be separated and identified using a technique called paper chromatography.
