In column chromatography, nonpolar compounds move down the column at a faster rate than polar compounds but when carrying out a tlc protocol, we can see that nonpolar molecules move up the plate more rapidly than polar compounds that move up the plate at a slower rate or dont move up at all. Thin layer chromatography and column chromatography results. Instead of a solvent being allowed to drip through a column under gravity, it. This video is about the column chromatography lab of the amgen biotech experience. Chromatography is using a flow of solvent or gas to cause the components continue reading paper chromatography report. The purposes behind the chromatographic experiments was to separate and extract pure pigments from mixtures. Hints for the answers to the proposed questions and topics to discussion. The purpose of this laboratory experiment was to separate pigments found in spinach using a microscale column. Column chromatography is gravity driven, so the more solvent on top of the column, the faster the solvent travels down the column. Experiment 3 tlc discussion thin layer chromatography. The results show that polarity of the eluent is the deciding factor as to how quickly a component of a sample will travel down a column for a collection in column chromatography. As depicted above, the analyte is loaded over the silica bed packed in the. Thinlayer and column chromatography were used to achieve this goal.
To separate food colorings into their component dyes. Some of them include column chromatography, thinlayer chromatography tlc, paper chromatography, gas chromatography, ion exchange. Those isolated pigments were then placed on a thinlayer chromatography sheet and analyzed using tlc. Chromatography lab report essays 667 words bartleby.
Experiment 3 tlc discussion free download as word doc. Formal report expt 5 column and thin layer chromatography. Learn vocabulary, terms, and more with flashcards, games, and other study tools. In the thin layer chromatography experiment, as the mobile phase rose up on the tlc plate it dragged the ink from the marked dot up along the tlc plate. Conclusion in the thin layer chromatography experiment as. The pigment that was closer to the marked dot was more attracted to the stationary phase, the silica gel. Pigment separation with chromatography lab conclusion. Conclusion the purpose of this experiment was to separate. Polarity and the affinity the solvents mobile phase had towards the silica gel stationary phase were very important in the separation processes. Conclusion the purpose of this experiment was to separate ferrocene and acetylferrocene using column chromatography. Paper chromatography introduction the purpose of this experiment is to observe how chromatography can be used to separate mixtures of chemical substances. The solvent cannot fall below the stationary phase because the column will dry out, making cracks and air bubbles, so the column will not run as well. Doc chromatography lab report vlada panina academia. Separation, purification and identification of the components of a.
