Words: 1298 (6 pages)

Abstract Pigments extracted from different greens have different polarities and may be different colors. Mixed pigments can be separated using chromatography paper. Chromatography paper is able to separate mixed pigments due to their polarity and solubility. Pigments of chlorophyll a, chlorophyll b and beta carotene will be separated on chromatography paper because each has its…

Ink Paper Chromatography


Words: 960 (4 pages)

Ink Chromatography Lab Background Information Paper chromatography is an analytical method that is used for separating and identifying mixtures of substances into their smaller parts. Paper chromatography works because the ink used contains several dyes (pigments) that when place on porous paper are dissolved in a solvent by capillary action. When the pigments (solutes) are…
