   2 maj 2024 · In this experiment, pigments are extracted from spinach leaf and analyzed and separated by thin layer chromatography (TLC) and column chromatography (CC). Spinach chromatography allows the separation of substances from a mixture based on the different affinity that these products have for the stationary phase (silica gel) and a mobile phase ...

   An example is the spinach leaf, which appears dark green, but is actually a mixture of several pigments of different color. In order to identify the individual pigments, chemists use a technique known as chromatography (‘chroma’ refers to color) to separate out the different pigments.

   28 wrz 2021 · How Leaf Chromatography Works. Paper chromatography separates pigments in leaf cells on the basis of three criteria: Solubility; Molecule size; Polarity; Solubility is a measure of how well a pigment molecule dissolves in the solvent. In this project, the solvent is alcohol. Crushing the leaves breaks open cells so pigments interact with alcohol.
