Those isolated pigments were then placed on a thinlayer chromatography sheet and analyzed using tlc. This video is about the column chromatography lab of the amgen biotech experience. Download as docx, pdf, txt or read online from scribd. Experiment 3 tlc discussion thin layer chromatography. Thin layer chromatography and column chromatography results. 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. 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.
Chromatography lab report essays 667 words bartleby. Conclusion the purpose of this experiment was to separate ferrocene and acetylferrocene using column chromatography. Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. The purpose of this laboratory experiment was to separate pigments found in spinach using a microscale column. Some of them include column chromatography, thinlayer chromatography tlc, paper chromatography, gas chromatography, ion exchange. Paper chromatography introduction the purpose of this experiment is to observe how chromatography can be used to separate mixtures of chemical substances. The purposes behind the chromatographic experiments was to separate and extract pure pigments from mixtures. As depicted above, the analyte is loaded over the silica bed packed in the. Polarity and the affinity the solvents mobile phase had towards the silica gel stationary phase were very important in the separation processes. Column chromatography is gravity driven, so the more solvent on top of the column, the faster the solvent travels down the column. Doc chromatography lab report vlada panina academia. 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. To separate food colorings into their component dyes.
Learn vocabulary, terms, and more with flashcards, games, and other study tools. Hints for the answers to the proposed questions and topics to discussion. Chromatography is using a flow of solvent or gas to cause the components continue reading paper chromatography report. Conclusion the purpose of this experiment was to separate. Formal report expt 5 column and thin layer chromatography. 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. 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. Separation, purification and identification of the components of a. Instead of a solvent being allowed to drip through a column under gravity, it. Thinlayer and column chromatography were used to achieve this goal. If an eluent traveling through a silica gel is less polar, the less polar component will travel down the gel quickly for collection, while the polar component stays stationary in the gel. Experiment 3 tlc discussion free download as word doc. Column chromatography and tlc of spinach group experiment 3 individual lab report save as pdf and submit, due by 12.
