What is chromatography- Chromatography is the separation of mixture by passing it in solution or suspension or as vapor. It’s a technique for separating mixtures into the components this needs to happen in order to do the 4 things analyze‚identify‚purify‚quantify. Many scientist use this to do the 4 steps. When analyzing its used to examine the mixture and to find out the relation with one another. In purifying you need to seperate or take away and put it by itself for further study. In identifying

Plant Pigment Chromatography VII. Analysis (Questions) 1. What factors are involved in the separation of pigments? Factors that are involved in the separation of pigments can include pigment solubility‚ the attraction between the pigments and paper and the size of each pigment particle. Because of these factors the results were as they were. Beta-carotene traveled the furthest because it forms no hydrogen bonds to the chromatography paper and is slightly soluble in the solvent. Contrastingly
