o This diagram below shows the results of a simple paper chromatography experiment to identify the pen used to write a message. M comes from the ink used to write the message, and 1, 2 and 3 are from three possible pens that might have been used. Which pen might have been used to write the message? Explain why. height reached by the solvent: the "solvent front o This technique can be also used to identify particular amino acids in a mixture of amino acids. However, these are all colourless. You can dry the paper and then spray it with something like ninhydrin to make the spots visible. A mixture of amino acids (M) was tested against five known amino acids (1 to 5) and the following chromatogram was made: What amino acids were contained in the mixture M?

Iman has a mixture of two compounds A and B. A is a protein, and B is a lipid. He plans to separate the mixture using a column chromatography technique. He packed the column with amino bonded with siloxane material and use a mixture of 20:80 of water: hexane as the mobile phase. i) Sketch the apparatus set up for the chromatographic technique used by Iman. Use the correct chromatographic terminologies to label all of the apparatus, materials, and phases. ii) Predict the sequence of elution when the mixture was loaded onto the separation column. Justify your answer. iii) After the first compound was eluted, Iman discovered that the second compound was taking too long to pass through the column. Please suggest any strategies that could be used to aid the elution process.

You are assigned to separate a mixture of colourless amino acids present in protein molecule, using chromatography technique. You have a chrome paper (Filter paper sheet), TLC plate, chrome tank or beaker, Solvent (Hexane) and the mixture of amino acids. Answer the following questions related to your experiment. (a).

You run the chromatography system with paper as the stationary phase and 70% isopropanol as the mobile phase. You determine the Rf of a polar analyte to be 0.40. If you use 100% isopropanol (a less polar solvent) instead of isopropanol as the mobile phase what would you expect to happen to the Rf value? No value effect on Rf higher lower could be higher or lower
