Additionally, the preparation process can alter the RF value, such as by failing to fully saturate the chromatography chamber with solvent vapor. The specific mobile and stationary phases dictate whether chemicals go faster or slower and how they are separated based on the component's properties. The other two pigments are types of carotenoids, which appear yellow, orange, or brown. Some are reddish, while others are dark greenish. Here are the distances travelled by the solvent and the pigments: \(\text{Rf for chlorophyll b}=\dfrac{3.8\text{ cm}}{9.9\text{ cm}}=0.38\), \(\text{Rf for chlorophyll a}=\dfrac{5.3\text{ cm}}{9.9\text{ cm}}=0.54\), \(\text{Rf for xanthophylls}=\dfrac{7.6\text{ cm}}{9.9\text{ cm}}=0.78\), \(\text{Rf for carotenes}=\dfrac{9.7\text{ cm}}{9.9\text{ cm}}=0.98\). If a mixture of compounds is separated using solvents, as mentioned above, then different spots will show up on the chromatography paper. Keep the spot as small as possible.

So, often a mixture of solvents is used to obtain better separation of pigment bands. The pigments flouresce at a lower energy level than what they absorb, so the chlorophylls flouresce a red color (red has the lowest amount of energy of any of the colors in the visible spectrum).

Plants in different environments have evolved to make different proportions of these pigments to maximise light absorption. The top band of pigments in the separation are carotenoids called carotenes, most likely beta-carotene, and appear yellowish-orange. RF, or Retention Factor values, are fractions used in chromatography, representing the known fraction of the total distance traveled by the solvent that the given material will travel.
