Separation of Chlorophyll a, Chlorophyll B, and Beta Carotene by Paper Chromatography


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 Chromatography Lab Background Information


Words: 761 (4 pages)

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 dissolved in the solvent (water…

Paper Chromatography


Words: 1458 (6 pages)

Abstract Paper Chromatography uses a chromatogram paper as its stationary phase and the solvent as the mobile phase. Retention factor is the ratio of the distance travelled by the sample to the distance travelled by the solvent. This experiment aims to separate organic compounds, to compute Rf values and to identify unknown compounds using Rf…

Lycopene Lab Report




Words: 367 (2 pages)

Introduction: Lycopene is a carotene because of its carbon and hydrogen composition. It is red in color and a member of the carotenoid family. Members of the carotenoid family play integral roles in plants. They use the absorption of light to aid in photosynthesis, and protect chlorophyll from damage. In humans, Lycopene acts as an…

What is a chromatography essay?
Chromatography is a technique for separating mixtures into their components in order to analyze, identify, purify, and/or quantify the mixture or components.
What is chromatography in your own words?
Chromatography is a process for separating components of a mixture. ... The different components of the mixture travel through the stationary phase at different speeds, causing them to separate from one another.
What is the importance of chromatography in our daily life?
Chromatography is also used to help catch criminals. In line with programmes like CSI, gas chromatography is used to analyse blood and cloth samples, helping to identify criminals and bring them to justice.
