WebPaper Chromatography. One of the first-ever practical experiments you probably carried out in chemistry at school is a simple example of paper chromatography: separating a coloured ink. You draw a pencil line across the bottom of a sheet of paper, place a dot of ink on the line, and place the paper upright in a beaker of solvent. WebIf you look closely, you may be able to see that the large central spot in the chromatogram is partly blue and partly green. Two dyes in the mixture have almost the same R f values. They could equally well, of course, both have been the same color - in which case you couldn't tell whether there was one or more dye present in that spot.
WebThere are two phases of chemicals in chromatography, the stationary phase and the mobile phase. The stationary phase is the substance that is used in the "background" so as to carry the mobile phase molecules. The products in which one is trying to observe will travel in the mobile phase through the stationary phase. WebMay 3, 2024 · How to calculate the Rf values of amino acids? After some time, mark the center of the spots, then measure the distance of the center of the spots from the origin and calculate the Rf values. The Rf values with butanol-acetic acid- water solvent are as follows: alanine 0.24, glutamic acid 0.25, glycine 0.2, leucine 0.58, valine 0.4, lysine 0.58 ...
