Introduction Chromatography is a technique used to separate a mixture into its individual components. In this experiment‚ chromatography is done by using a thin layer chromatography (TLC) plate and filter paper. The word ‘chromatography’ itself means the separation of colours. However‚ nowadays‚ both coloured and colourless compound are used in chromatography by various methods. In chromatography‚ the separation process of mixture is mainly based upon the polarity and molecular weight of sample

Resolution of Matter into Pure Substances – Paper Chromatography Abstract The purpose of this laboratory was to determine how different substances have different solubilities in a given solvent. This was accomplished using the method of chromatography. The solubility of each substance was first determined by dropping a drop or two of each on a line drawn 2 inches above the bottom of a piece of paper. Then the paper was lightly bent in order to tape both sides of the paper leaving about a 4 centimeter

drug using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done on a plate that is coated with a layer of absorbent

must you use lead pencil‚ instead of a pen‚ to mark your chromatography paper? A lead pencil should be used instead of a pen because the ink of the pen would dissolve in the eluting solution and separate. The components of the ink could mix with the other ink/ dyes that would be tested on the same chromatogram. Thus‚ a lead pencil should be used. 2. Why should you avoid touching the surface of the paper to be used for amino-acid chromatography? We should avoid touching the surface of the chromatogram

Task 3: How could Thin Layer Chromatography (TLC) have been used to prepare a pure sample of aspirin? The method of using thin layer chromatography is easy‚ quick and relatively cheap to carry out this makes it ideal for preparing pure samples of aspirin. Equipment Required: • Thin Layer Chromatography Paper • Ruler • Pencil • Solvent • Beaker • Micro Capillary • Access to a fume cupboard • UV light • Clingfilm • Individuals sample of aspirin • Pure sample of aspirin • Sample of salicylic acid Method:

it is possible to identify which peak correlates with which compound. Figure 2 contains a peak at around 500 and 700 nm which is a good indicator that that would-be chlorophyll b. This makes sense because this was the bottom band from the thin layer chromatography and chlorophyll b is the most polar compound. Chlorophyll B contains an aldehyde where chlorophyll A has a methyl group making it slightly more polar. Following that‚ figure 4 contains

Column and Thin Layer Chromatography Beverly Abstract: Plant pigments were separated and concentrated from a crude spinach extract through the use of column chromatography and an eluatropic series of hexanes‚ hexane/acetone‚ and methanol. The pigments were analyzed using thin layer chromatography with a 30% ethyl acetate/hexane developing solvent. Introduction: Chromatography is a technique used to separate a mixture of two or more components based on

the lab is to separate the caffeine samples we are using‚ using thin layer chromatography. The solvent we are using for the separation is 3:1 mixture of Chloroform and Acetone. Principle: Thin layer chromatography (TLC) is an important technique that is useful for separating organic compounds. TLC is often used to monitor the progress of organic reactions and to check the purity of products. Separations in Thin layer chromatography involve distributing a mixture of two or more substances between
