    Separation of Amino Acids by Cation Exchange Chromatography Introduction and Purpose: Amino acids are small biomolecules that have a carboxylic acid backbone in common‚ as well as an amino group attached to a saturated carbon. There are many amino acids‚ but there are 20 most commonly know amino acids. Amino acids are the fundamenta building blocks of other biomolecules like proteins and ezymes (Davidson‚ 2015). This experiment examined a mixture of 3 amino acids. The purpose of this experiment

    Problem How can you tell pigment separation by using Chromatography? Objective To prepare a chromatogram‚ separate pigments in a leaf and interpret the chromatogram. Hypothesis If I am to put a chromatography paper into a solvent‚ then it would separate the pigments depending on their Rf value. I think the pigments will separate in this order: Chlorophyll A‚ Chlorophyll B‚ Carotene‚ and Xanthophyll. Introduction Chlorophyll is the molecule that absorbs sunlight and uses its energy

The reason for conducting the research is to know how the colors of our favorite candy-coated sugary rewards came to be and that method of knowing is what we call “Candy Crhomatography”. Chromatography by definition according to Webster’s dictionary means “ a method for separating the constituents of a solution (gas or liquid) by exploiting the different bonding properties of different molecules”. In this case‚ the molecules being broken down

    Chromatography: Separating Mixtures Introduction: Magic marker inks are often mixtures of several compounds. Paper chromatography is a common method of separating various components of a mixture. After separation‚ you can observe the different colors that make up a particular color of magic marker ink. You can also calculate a ratio Rf‚ which compares how far each compound traveled to how far each solvent (substance that dissolves another substance) traveled during the experiment.

    Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by
